Okay, say you do it. Say you go along with Crowley's plan, pay the price, step away from those you love, you'll be powerful, enough to strike down Raphael and anyone else who opposes you, what if you decide then you like it, you don't want a life outside. What if you decide Hell is just, there for the taking.
Just think about what you'd be giving up. With perhaps no hope of return. Is it fair that you make that decision alone
