no i understood, maybe i explained sh!tty, obviously if you cant heal from an attack, you dodge, Orochimaru doesnt want to die, dying throws a wrench in most peoples life plans, of which Orochimaru has many. Having your throat slit and your face crushed repeatedly will kill you if you cant shed skin like he can, but despite this, he sits through the pain and trauma of that beatdown and gets up smiling just because pain doesnt bother him anymore.
Oro is a ****ed up dude, hes seen the darkest parts of shinobi history, and hes down for anything.
