Your parents have nothing to do with it. You are a man now. Make your own mind up. If (as someone has said here) you have taken the shilling, you have taken the war.
Old men make wars, young men have to fight them.
You get killed ? Sad, but that's what happens in wars. Grief is pointless - the war goes on without you, that's all.
'Twas ever so, and ever shall be.
