[DC] Why exactly is John Constantine so dangerous ?

Simply curious if he is dangerous because of luck meeting meticulous preparation or if he has innate magical talent like scarlet witch. Overall just curious to hear your thoughts.

Cunning. John Constantine isn't the DC universe's most potent mage but he's absolutely the one you least want to mess with. That's because he improvises on par with the Batman and has the morals of Amanda Waller. If Johnny-boy decides he wants to screw you over, you're going to get screwed over.
