Just because I own guns doesn't mean I agree with people misusing them. Lumping responsible gun owners in with the evil people that would no doubt do it no matter what the rules, though, is wrong.
I hope you own guns because of polar bears near you. Other than that, I can't think of a reason - any reason - people feel the need to own guns. The sad truth is many of the tragedies and accidents involving guns came from those which are obtained legally. Just a few days ago, a young 4 year old was shot dead by another 4 year old accidentally. If the guns were not so abundant, many of these accidents wouldn't have happened.
