Hi Heribert, and welcome to the board.
The line I'm thinking of is quite a bit different than what you've posted, but if the quote you're looking for
is from an Eastwood film, then this is the closest to it that you'll find.
WILL MUNNY: All right now, I'm comin' out. Any man I see out there, I'm gonna kill 'im. Any sonofab*$@h takes a shot at me, I'm not only gonna kill him, I'm gonna kill his wife, all his friends. Burn his damn house down. Nobody better shoot.
And as he mounts his horse outside, he yells:
You'd better bury Ned right! You'd better not cut up nor otherwise harm no whores! Or I'll come back and kill every one of you sons of b*$@hes.
These lines are from the last scene of Clint's Academy Award winning western
Unforgiven (1992). They're spoken by Eastwood's character, William Munny, as he's leaving Greely's Saloon where he's just killed the town's sheriff Little Bill Daggett (Gene Hackman), most of his deputies, and the proprietor of the saloon, Skinny.
Hope this helps.
