I actually went and asked on Hexbear their opinions about this and tried to dig a bit to understand the logic. I don’t agree with it and I think their logic is cold, brutal and lacking in empathy, but there is a logic.
Essentially, they support Russia critically. This means they agree with any normal person that Russia is a shithole, but it’s a useful shithole that challenges NATO. They see this as a proxy war between NATO and Russia, and the more they can bleed each other the better, especially if it weakens NATO. The civilians who are caught in the middle are acceptable collateral damage according to them.
