they are toxic people they want to be on top of others ,because of their own lack of confidence and because of their own problems in life caused by either others or them selves. sometimes they grew up with toxic people ,,see desc<x>ription for toxic people.even if they try they can not stop blaming others for small stuff.
They have a need to feel superior on some level...
I think some people just have issues with the past themselves. They don't want to feel like the only ones that have screwed up beyond repair. That or they have problems sticking to their own business.
clinging to indignation creates a mirage of superiority
Because they are ********. They are vicious creatures that enjoy seeing others writhing in pain. Stay away from them.
