Severus Snape hated three people most in his life:
First, Voldemort originally wanted to follow him seriously to become bigger and stronger, but who knew he would become more and more crazy. Being crazy is just a way, but it is not a way to live in the world;
Second, Albus Dumbledore, this old man understood all my jokes and stopped telling them, and he still tried to tease me;
Third, Serunity made me, who had no desires and no weaknesses, a weakness.
