Only if you dispose of the nazi carcass, by actually hosting a memorial (pro tip, if you spike the punch with methanol you can get more left over nazi parts)

If you leave the body out, as sort of a “scare nazi/scare crow” kinda concept, I believe that you don’t get the funeral director badge, but you do get to express your views and feed the local scavengers. May I suggest https://en.wikipedia.org/wiki/Capital_punishment#History for further inspiration.
