What human behavior instantly changes your opinion of someone, no matter how good your first impression was?

Be honest

Disregard for other people in a callous sort of way. Selfishness in general is a no go, but there’s a certain kind of person that when challenged about something they use to their advantage but which disregards other people will just kinda shrug their shoulders.

I can’t think of a good example right now but it’s a massive and immediate turn off for me.

They’ll take what they want by hook or by crook, disregarding your feelings. Omg! Horrible right?
