Those people are stupid, don't let them get to you. Anyone who complains about Kratos as you are beating them is a scrub - keep that in mind. I've played games where I outplayed the opponents every given opportunity, and yet they still blames their loss on "Kratos being cheap." He isn't even the best character. He receives a way unproportional amount of hate. I personally enjoy all the crap people say about Kratos as I destroy them with him because it gives me something to laugh at.
