Now now, hate leads to suffering.
Yeah Palpatine's so weak and unprepared that he created the Galactic Empire before being FOUND by the Jedi as the Sith lord.
Palpatine knows what is going on and what will happen. He can sense the future, as Yoda is asked to and Anakin can more on instinct. Palpatine has telepathy and influences others subconsciously, dreams and fear, etc.
How is Anakin going to culminate his turn to the dark side other than striking Windu? There aren't many better ways.
