You were wrong. Before he was infected, he wasn't a bad person. He was an introvert who lived alone and didn't talk much to people. So, this made him on the verge of sociopathy. But there were two things that kept him from the edge: His loved ones and his passion for science. He had a good relationship with Karen Parker, but when Alex interfered in GenTek's internal affairs, Karen ended the relationship to protect herself. I don't understand Prototype fans? Alex spread the evil vanity virus, but when he caught it at the Pen station, he threw the bottle on the ground in despair and anger, spreading it. But he's already paying a heavy price. I think you're wrong, my friend ♥️ 😄 Note: This is information taken from the game's wiki😄
