because that makes them feel good about themselves
Depends on how the critics are
'cause criticizing themselves is difficult
they can find nothing to critisize themselves abt and even if they didthey couldnt admit it to themselves much less u
because they can
They feel/have conflict within themselves that they have to retaliate when threatened by others.
its easier to do when others agree with their criticisms
Been that way since forever, human nature I guess.
Because some need to have their giant egos tucked to bed.
