Not really. Peter specifically says "some of them are going to die". Strange specifically says something to the effect of "if they die, they die."
It's not that Strange is trying to get them killed by sending them back, it's that he doesn't care whether sending them back gets them killed or not, he just wants them back where and when they were.
As for Marko; nobody is in a position to know whether he survives or not since he's the furthest along in that timeline, that is until Tobey-Peter shows up, but by then it's academic.
