Would it? I think some times that compared to other men(heroes) in the marvel universe, Spidey is known the most as the most unprepared for fatherhood due to being known as the man child of the group. BIut I notice that Wade Wilson has a kid and despite is wonton immaturity is a good father to his daughter when they are together. So spidey should have no problems raising a kid, but only if he changes in a big way and pretty much stops being the spiderman we all know and love in general.
So what do you think?
