I didn't buy it. Even if what he said is true (That's how his father did it and it's a Mitchell tadition), I thought Phil hated his dad and didn't want to be anything like him? Combine this with the fact that Ben is risking his life to save Phil...
I'm not saying Phil was lying about his reasons, but I just thought the writing was unrealistic that Phil would actually do this, and not even show any remorse or conflict over it.
