is it my moral ocd or am i a monster?

When I graduated high school I gave up my server to my younger moderators (owners were 14 and 16, rest of the mod team was 15/16/17) because I got too old to run it anymore (i was 18). It was a simple SFW art and roleplay server. But I feel horrible for giving that responsibility up to people who were younger. I remember I checked in and everybody was inactive, so people were acting up/breaking rules. 

I shut down the server and explained to the new owners when they came back what went wrong, as well as what new rules to establish if they wanted to lift the shut down. I just feel bad and like a groomer. I made it known that since all of the staff was inactive and they were minors, they should not run the server alone and just delete it. They agreed but they're making a new seperate server of their own. 

I wish I never gave them that responsibility. I remember I was very frustrated when I found out that the other staff members weren't helping. I discussed new rules to be implemented such as more emphasis on what no nsfw means (found out someone sent a story they made that was gorey/suggestive and i immediately banned them) and how adults/minors shouldn't be roleplaying romance with each other, but i think looking back that was far too serious to ralk about. I just wish I never made that stupid decision of handing the server down to new owners. 

i know its probably just my ocd but i really can't tell anymore. am i a monster?  im terrified of being like my groomer.
