What makes you think Crowley would stand a chance against Roman?

Roman>Edgar>regular angels. We've never seen Crowley display the power to kill angels and even with Cas backing him he wanted nothing to do with Eve, who by the looks of things wasn't as strong as Leviathans.

Jesse always bugged me. He's the result of an ordinary demon and a human mating, what makes him so powerful? Assuming Cas wasn't exaggerating about killing every angel on earth thing - that's some serious power.
