What is Gon's rage?

When Kite died facing Neferpitou, Gon blamed himself for being too weak and entered a destructive and self-destructive spiral. During this descent into anger, he became extremely vengeful and single-minded, only focusing on making Pitou fix Kite, and if it weren't for Killua, he would've likely gotten Komugi killed.
