@RogueJuggernaut: Yeah they agree on some points (mostly on the bit that he is to melodramatic at times, I also think he is a tad whiny at times, but it is no worse than Batman). Many people I have seen on here and on other site and many of the reviews around the internet love the series,. But why don't you pick up another series if you are bored with this one? There is plenty out there with heroes that kill, pick up some of the early spawn issues by Todd McFarlan I bet you would like those :) or maby you will find the new Spidey ongoing better?
Also Kaine is not a carbon copy of Spider-Man far from it, they are like twins but with completly different mindsets, Kaine is dark and brooding, Peter used to be light and warmhearted (Spock is another story).
Kaine don't take pleasue in what he is doing and if you have read scarlet spider 13 he even scares innocent girls to keep them safe, something Peter would never do. Kaines series also deals with themes to dark for the more mainstream Spider-man series (like the recent humantraffic stuff). Also Kaine is a lot more violent he don't care if he breaks someones bones or sends them into a coma.
I still think he would be willing to kill, but only if it realy counts and there is no other option. Something Peter never ever would do under any circumstance. (and mostly I think Kaine do not kill out of respect from his brother Peter, and also if you where given a second chance in life, it would be a waste to go back to your old self. And not trying to be something bigger and better than before. Showing compassion is a greater gift then killing).
Saying he is boring because he don't kill would be the same as saying Iron Man is boring because he stopped drinking.
But allas maby we can agree to disagree. :)
