Hey, someone told him not that long ago that maybe he should try this hero thing once in a while and okay, it's not boring. In fact, he might be having a little too fun with it, tearing and punching at whatever part of lizard he can get a hold of, feeling a sense of liberation he hasn't experienced since he realized he can punch non-humans in the face without the chip acting up.
The thing about being dead is that you can have a big dumb lizard bite deep into your arm without it doing all that much damage, allowing you to punch it really hard in the eye until it lets go. It's a neat little tactic and one he's deployed without much thought about how long it takes to heal here. Still, if it works it works and before long he snaps the raptors neck, leaving one straggler left standing.
