You'd gain nothing by putting up a fight.

They're loaded.

All you've got to do is jerk the hammer back and pull the trigger, and the best way not to miss is to hold the muzzle underneath your chin--this way--keeping the butt well out from you.

You make sure when you do that.

The only satisfaction you'll have, if it comes to suicide as a last resource, will be that you've tried to do your duty and the knowledge that you'll be avenged.
