i used to know but can’t recall the exact translation i wanted.
At least Luther wrote (WA 56,323,19-24):
Quia Mortem occidi est mortem non reverti [...]
Clumsy translation: "For Death to be killed is death to not return..."
We could modify that phrase so that "I killed Death" = Mortem occidi. Funnily enough the first person perfect looks identical to the passive infinitive.
