I'd argue addiction hurts the family the most. Especially his wife and young child. That child is likely to have trauma they never fully understand why it exists.
There are plenty of options around it... and it isn't black and white/either or sort of things.
You can support the Avs while thinking Val is a POS. You can think both are POS. You can support both. Each person can make their own decision on how they want to view and reflect upon it. Any of us who have been impacted by addiction either directly or indirectly know that it is not a binary thing. There is a lot of grey.
Personally, I'm not blind to the fact that the Avs have a number of questionable characters currently in the org and have had in the past. The professional sports world has a really seedy underbelly to it, that if things really came to light, would shock people. The Avs are definitely not immune to it. I have things that I know that are very distasteful, and I understand it is just the tip of the iceberg. To me, I'll cheer for the Avs with or without Nuke. His morals or addictions really don't have any impact on my fandom. Nuke pisses me off personally because he's had a direct impact on the last two playoff runs in a row. Odds are he'll relapse and do it again too. Maybe not this year, but could be. Could be 2026. But I can understand that cheering for him leaves a bad taste in other peoples' mouths. It is not for me to judge whether people should or should not cheer for him.
On your last line, then you shouldn't be judging
@dahrougem2 for his objection either.
