Why would someone who is already in pain wish to inflict it upon others?

Misery loves company. People sometimes like to make the outside world look like their inner world. If they are in pain, the bring it to life in their surroundings. It's sad that they can't see how much more good it does to share love.

Because they want the victim to feel the same way they do. Or by them inflicting pain on others makes them feel powerful and better about themselves

These people have poor emotion management. They hold maladaptive beliefs such as believing that by seeing others suffer and be in pain, it would help to make them feel less alone - this is incorrect and only leads to a continuing cycle of sadness/anger.

Sometimes when someone is going through a lot, that can make them feel upset and angry. This could lead them to lash out on others or sometimes themselves. If you know someone who seems easily irritable or tactless, it could just be their way of letting out their emotions.

Someone who is in pain may wish to inflict others with it as they want some sympathy, and they need to know the this person has felt a pain as great as them in order to feel comfort in their words.

Because they want others to feel the same way they do . They don't want to be on their own. They feel vulnerable on their own

Sometimes people don't know how to react to their own pain. So the easiest way around that is inflicting it on other people.

because they want others to feel it as well. instead do what makes you happy. it helps... love something

I guess to just try and make others feel what they need to go through. Or make it so someone else is in pain with them so they aren't lonely.

Because they feel the need to make others feel like them, they want others to know how they feel, so they aren’t so alone

Maybe a way that he can desembocate or let out all the pain, but in a really bad way, it can be also a cry for help,

This could be because they feel that it will ease their pain when in reality, it makes it worse. This is not a good method of releasing your pain/anger

This happens due to psychological impact. I have noticed, many people who have had their hearts break by a particular person, would often make it a point to break other people's hearts in the same manner, so that it gives them solace. In the novel, Great Expectations, by Charles Dickens, one of the main characters, was an eccentric old lady named Ms Havisham. Many years ago, her fiance had run away on the day of her wedding, and since then she had been so mentally damaged, that she adopted a girl and raised her to be cold hearted, and made the protagonist of the story, Pip, fall in love with this girl and get mentally damaged the same way as Ms Havisham was. I feel, the main reason behind all this is envy and jealousy, and triggers of the past. Pain can occur to a person, when her or she lacks something, and it is natural for them to feel bitter towards the people who have the very thing that they lack. Hence, they can't tolerate that, and they feel like causing the same kind of pain to them. The mentality here is, "I never had this. Why is he or she having this?"

Maybe they feel like the whole world is already against them and that certain people don't deserve to be happier than they are. It is a bad mentality but it happens sometimes.

They may inflict it on others without realising and/or in desperation to show the person how they feel.

Someone in pain may want to inflict it upon others because they may feel as if everyone around is happier than they are, and they feel insecure about feeling the way they do.

I’d say it’s due to a lack of confidence in themselves. So they feel the need to put other people down to make themselves feel better

people cope in different ways, and most of the time it won't be in a nice way. personally, before i knew i had depression, i would lash out at people and instantly regret it. ill always regret it... maybe they do, too.

Because I care for him/her Because I am concerned about him/her And most importantly I love to think about him/her

Sometimes, people who are in pain want others to feel what they feel. It's like they don't want to go through it alone.

I think a lot of people that are already in pain lash out because they feel this pain. It is a way to forget their own pain and hurt someone else.

It could be that they would like to feel like they're not alone in their suffering. So knowing that others experience it too may just make them feel better about themselves.

They have experienced pain enough to want others to experience what they have. They want others to feel the pain they felt through the experiences they have.

Some people have cruel intentions - that's unfortunately just how the world is. Some people get a kick out of seeing others in pain. Maybe this person just wants someone else to feel how they do because they feel they dont deserve it (which doesn't justify it).

Perhaps that person wants others to know the pain he’s going through, to feel understood. That person may also feel wronged and seeks justice by hurting others

This is like bully. Often times the bully is feeling pain and they don't have anyone to put it out on, so they see people who are easy to target, then they usually go for those people.

Someone in pain would want to inflict pain upon others because they want others to feel their pain and understand them.

Individuals who are in pain often times spread their pain. They want others to suffer the way they are suffering because sometimes in their mind if they have to suffer, others do too. It can make them angry or feel left out when they see happy individuals.

So that other people would get to feel the that they are going through so they feel less alone or like no one understands them

When people are hurt they wanna take it out on others to make them feel better about themselves. Not all bullys are mean most of them are just scared
