you really think that "anyone who has not been an absolute saint their entire life" is a equivalent to "Devoid of any kind of feelings towards anyone else, he shouts, screams, cries and sulks his way through his petulant life"?

because i don't. i think there's quite a difference. everyone can be an arsehole sometimes, sure. but that doesn't excuse those that are consistently unpleasant. there's a clear difference. so you can distance yourself from the latter without having any problems with the former.
