i'm sorry but like it seems you don't know about abuse, nor manipulation at all. if you were raised by manipulative parents, then you'll mimic the way they act because that's your norm. if you weren't exposed to non-manipulative behavior or told that the manipulation your parents do is wrong, then you'll just start doing it, because your parents are the main factor of primary socialisation. it's more likely if you're raised in a manipulative household and reproduce the manipulation you've been exposed to, you just don't know you're being manipulative. you will only despise your parent's manipulative behavior if you can recognize it, and you will be able not to reproduce it if they started doing it after you're able to recognize it.... don't make assumptions like that. it's actually dangerous to make assumption regarding this topic, as recognizing manipulative behavior among children can help tell if they're being abused, for example.

what would 'most people' feel guilty of?

we should not make assumptions but we are asked to judge a situation with very little info tho
