It depends how you do it. If you use a trigger then there shouldn't be a problem if it's activated on present, if it's not present then you could put in the init field:
this && man1 aliveIf it's a repeating script, then you could simply put a breaker at one or multiple places (depending on how many times it loops). eg.
?!(man1 alive):exitShould do the trick, if it's neither of these then you will need to explain further. These may not actually work, but should do
