User blog comment:G-Monster/Pure Evil Proposal: Jeremiah Valeska/@comment-26833018-20190514220359

I'm not sure. Whether Jeremiah was psychotic before he was sprayed with that toxin or not, it wouldn’t change the fact that he became more evil after he was exposed. Before, he was obsessed with his brother and just wanted to trap him inside his maze forever rather than kill him directly. Some people might say his was brainwashed or something.
