Depends who is on each track, e.g.

- I'd let 5 people adults die to save one child
- I'd let 5 strangers die to save one friend
- I'd let 5 friends die to save one family member


But if we're assuming it's 6 random adult strangers, morally, yes I'd flip the switch and have 1 die rather than 5.

Legally it's a different issue as I suspect actively flipping the switch would make you legally responsible for that person's death whereas doing nothing (other than trying, somehow, to get the train to stop) would not.
