If by unscathed you mean continuing to damage their mind body and soul by denying their emotions, guilt, shame, and self loathing deep down, then this alcoholic is guilty as charged.
By running off and avoiding responsibility while the people and places get worse and more dangerous, and you are dying a little more each day, yes.
Recovering now, but yeah. It's not so scott free on the other side, the reckoning is a bitch.
Take good care of yourself. Alcoholics are merciless when it comes to doing the same.
