>>47711586Ghetsis was always genuinely evil, considering that he took in and raised orphans in isolation just to use manipulate them for his ambitions. Originally, he was a Faux Affably Evil character, a villain whose politeness is an act that only serves to enhance his evil. He only became mentally unstable after N and him lost to Hilbert, realizing that years of his hard work, money and planning went down the drain over some southern hick that just started his journey. That's enough to make anyone crazy.
