What if he was forcefully drafted.

Let's replace it using your moral compass.

Ukraine began forcefully drafting 18 yr Olds with Down syndrome and sent them to the front line. Should a Russian aggressor drop his firearm and allow the autistic child to kill him?

The argument was NEVER should this happen; war happens. It's naive to think it doesn't.

The statement was that anyone in his shoes would pull the trigger.

No one thinks war should happen, your ignoramus. The point is anyone would choose self preservation I. This instance, EVEN you.

Your just adding on all this hypothetical bullshit, "it shouldn't happen, but he's the aggressor, it's just a child." 

None of that shit matters. Stop being fucking naive. It's exhausting.
