Eric.

Seriously does he care about anyone or anything? Its like a critic said "never have a character that's and a hole and just that nothing more nothing less". I mean I get he was supposed train the dauntless members to be heartless killing robots but damn he is is a sociopath, I can't imagine him fitting in anywhere else. Candor, nah.Amity yeah f**cking right.Abnegation not in a million years. Erudite, Eric is obviously not anywhere near as sharp or intelligent as anyone in dauntless even the initiates, Tris basically let's him know he's an idiot at their target training, he gets pissed because she was right. Dauntless rules changed and it seemed standards did also. I believe if it were not for Janine taking over and using him he would be factionless. I know in the book he's originally in erudite but he seemed eager and stupid when it came to defeating and trying to one up someone.the wargames. Four took him out flawlessly. Tris when caught along with four aims gun and four takes him down again. Insurgent "Eric gets his azz beat part two". He told four he was useless without the gun, only to have not half a chance in he** of winning the one on one fight with four. When preparing to shoot the girl tried takes him down and he kicks her pissed again she got the upper hand on him, because she had no right to stop him from killing a little girl, again sociopath. Again tris is a girl. He was gross I thought at some point he would try sexually assaulting tris just to hurt four. I mean did he even like girls? He hated himself too it seems. Bad part, sorry but he was kind of good looking I'm sure girls have liked or been attracted to him somewhat right? Okay maybe not. On top of that he was just nasty had to say it again he seems like the type who would get aroused by inflicting pain so he could have raped someone they don't mention. He is or was the personification of a one dimensional character. Never nice, only happy or smiling when starting up sh**t or abusing others and watching their pain, mean all the time just because,jealous and resentful of anyone who is better at something than himself, enjoys killing others just because his character has nothing else to do.
