And tbh, I'm really not seeing or feeling the bad look here. Who would think it's a bad look? I would think most Ukrainians would honor him for what he did. I'm not in their shoes, so I can't say that with certainty tho.
Not for supporters of Ukraine, but for their doubters
The line would be "Yeah they can't find enough volunteers and people dodge the draft so they have to send amputees out there"
That said, apparently in the US military there have been amputees who have returned to active duty, even combat deployments, so I guess you can counter with that.
