Why am always bullied by my roomates but at the end they always play victim.Making look like a bad person?

They either have experienced it or have seen someone experience it giving them A guilty conscience reason they flip the victim role on themselves. Rather than owning up to them having or experiencing a mental issue. These kinds of people make an issue with innocent people to making themselves not feel alone or alone with feeling the same way . These people you may address but not all of them will own up to it but trying is better than just continuing to allow someone verbally abuse you. These people usually have past traumatic experience so it’s easier to use your experience with them to address it .
