Matt and Frank are ALWAYS intense with each other. I can't see them truly hating each other, no matter what.
THIS. In spite of Frank dislocating both of Matt's arms (but not killing him) in Confederacy, he still spends a lot of time trying to explain Frank's code (read depth) to Spidey and Wolvie (read to the general audience). Ennis tried via DD to speak some sense to the masses, but Frank Castle continues to be an acquired taste. ;)
