Turns out your friend here is only MOSTLY dead.
See, mostly dead is still slightly alive.
You don’t shoot Lee Marvin, cause, even if he’s 99.92% dead, he’ll still pull himself off the floor, unleashing an unholy can of whup-ass.
Even if you shoot him on the grounds of a deserted Alcatraz, a great place for a nasty lil’ double cross.
Bringing the heat as only he can, Marvin oozes self-confidence and do-not-mess-with-me-boy attitude, working his way up the underworld chain of command, guns barking.
A nattily-dressed Grim Reaper is on his way, and he makes damn sure you’re 100% dead.
