They certainly don’t get to claim any kind of moral high ground, but as a bystander I can feel empathy for someone hit by a drunk driver, even if the victim had driven drunk before in the past.

Any increase in human suffering is unfortunate, regardless of one’s take on just desserts or karma or whatever.

I’d say it’s more like a high-profile NRA member getting shot. Unfortunate but it’s hard to miss the irony.

That’s fair, similar point. Reasonable people can both appreciate the irony and feel bad for the victim. Few people IRL have the sociopathic “they had it coming so I just want to watch them bleed out” attitude that we see so much of online.
