We don't actually know what he wants. As a representative of the Empire he wanted to support their rule, but as an independent operator his goals may he very different. Maybe carving out his own little corner of the galaxy and keeping it cut off from any future conflicts will suffice for him.Sure there is. He wants the galaxy stable.
Since when does Palpatine want him dead?He isn't just going to sit it out, and he can't "be around" without having a significant impact on events. And Palpatine wants him dead. So if he aint dead he is still stuck in a different galaxy.
