The russian soldiers are in an awful predicament in this war. But they are still the aggressors and Ukraine has the right (obligation even, seeing what Russia tends to do to civilian population it conquers) to defend itself against them…and as awful as these weapons are, they have not been used in an illegal way here according to international law (something that Russia doesn’t give a flying fuck about, btw.).
Personally, I don’t see a moral issue here though I of course would prefer if noone had to die of which only happens in the case of Putin withdrawing his troops right now.

The vast majority of them could simply not have volunteered. Also, you can surrender.

He can surrender, like many already did.

You always have a choice. There may be consequences of that choice, but you are never forced to take up arms and take the life of another person.

Again, I’m not trying to minimize or act like the consequences of that choice might not be severe, but the point remains. Each of us has a choice to make, and “just following orders” has never excused acts of evil.

Are their shoes tied together or something?

Well, they can surrender.

Not all of them all the time, but a lot of them are smart enough to do something “dumb” like drive to a Ukrainian village to ask for directions and “get taken as pows”.

So yeah, yes and no, as the answer to your question.
