He can't say that he did it because he had wanted to. It was just an urge.

A terrible, carnal urge that...Eugene didn't even know he had until that man in the hood came. Life had been normal for him, where he had been sitting there, at his computer screen, watching around the city for any D.U.P. activity that could be lurking. They didn't need a repeat of what had already happened before.

And, seemingly out of nowhere, there was this scream over one of the lines. When he had tried to find a good view of the location through nearby cameras, it had been startled him, to say the least. But he brushed it off as a new conduit that had some vague control over electricity.

It hadn't even occurred to him until a couple of days later, when he was out on a 'top secret mission' with Delsin and Fetch, that the source of that scream he had heard, would rear its ugly face. Or, partially hidden face.

He had been shoved so hard against the nearest brick wall that he could actually feel his brain shake in his head, and it had been enough to make him feel sick to his stomach. He'd never admit that anything happened, but he could never forget how that deep voice had rattled him to the core. He'd never forget how he could see those piercing, vivid red eyes bore into him in the fading sunlight, nor how those words had caused this new feeling inside of him.

Never had he felt so unlike himself. Never had he felt so...demonic.

Since that evening, he kept himself sealed shut within his dominion, away from prying eyes, and away from reality. It's the only way he knows that the man in the hood can't find him, and can't traumatize him more than he has already. But, even then, it hasn't stopped him from 'accidentally' unleashing a few of his demons on the civilians who haven't done anything wrong…

And it's never stopped him from siding with a few of the 'bad guys' to get stronger weapons, or to level up faster.

...When he figures out what's wrong with him, he will find the man that managed to corrupt part of his mind, and he will put a stop to him. Until then, he needs to satisfy the urge to grow stronger, and that's exactly what he's planning on doing.
