US & Canadian troops routinely shot Waffen SS troops trying to surrender after they killed Canadian and US prisoners in Normandy.
I seriously doubt Ukrainian forces are being better treated by the Russians.
I would also point out that troops are not under any requirement to accept surrender if the captured troops cannot be secured.

#2. So, by your own logic, it is now OK for Russians to execute Ukrainian POWs.
