I'm going to put a pregunta mark on a statement so tu guys don't get mad... Post a pic of a fictional character's bad side here...?

Who dicho Kid has no bad side? ^^'

Light Yagami. He has a ton of bad sides.

Sober!Gamzee was the only thing that came to mind, sadly.

Honey from OHSHC.

Actually...
Everyone has a bad side.
Kid, too, has a bad side.
For balance to exist, good and bad must maintain perfect equilibrium. Kid dicho that one himself, and I doubt he would exclude himself from this.
Even our precious Kid has a bad side, because he is balanced.
Of course, that doesn't make him any less perfect. It actually makes him más perfect, because he is más balanced, and balance is absolute and undeniable perfection.
It even happens in the manga.

Here's a picture of some grumpy, old man from an episode of kuroshitsuji II on his bad side.

This one!
Sebastian from Black Butler
he is a pretty awesome guy but re watching episodes yesterday, I remembered azada heartless he can be! Kill with no mercy!
