1. I'd die, becoming a Necron would be so torturous
2. Serve chaos, ok sure you'd be hunted by everyone in the Imperium but the rewards would be incredible
3. Die, being a DE slave would be worse than death
4. Fight to the finish, I mean chances are I'll die anyway, I may as well try and take some Tyranids with me
