Thanks for the advice. Also, it's more like dude has just got the worst luck. First he's been tormented by Jake so much that his perception is warped. Next he's preyed upon by Ella and given a monster pill. If he was able to defeat his demons and command Jake to do things the first time, then maybe he would've been satisfied with that and become a normal person. But then Ella got pissed off (I suspect it's probably because she went through the same experience and loathed seeing it happening to one of her underlings) and brutalized him some more, completely destroying his sense of self and replacing it with hers. Remember, she explicitly told him to ditch everything - his friends, his morals, everything - and just pursue power. She even misleads him by talking about the MC as if he's surrounded by girls only because he abused his power, which to be fair his new appearance did help a lot, but the main reason is also because he isn't an asshole. She intentionally set the MC up as a rival or even a nemesis to be defeated. Like seriously, Ella's got issues.
On top of that, she gave him the ultimatum: Fail, and she'll kill him herself. Long story short, normal Jake would not have done such a thing. At the very least, he wouldn't use his powers on his friends or the MC's friends (the fact is he never used it maliciously against anyone except Jake until Ella beat him, and even then the order he gave to Jake then wasn't malicious per se). The brutalized and brainwashed (in the figurative sense) Jake though? What can't people not do when they're desperate? Frankly, Ella's the root of the problem here. What the hell is even her problem, seriously.
