The second example, killing others with allies in combat, seems to be similar to team sports. However, the third one, being held in captivity / abused, seems to be different in kind. Do you have any sources on it?
Edit: I wonder if playing a team-based competitive game like Team Fortress 2 has any effect on oxytocin levels, in addition to dopamine effects that are typical for video games?
Hmm, this is surprising. At first I thought you’re providing examples of bonding behaviors that don’t raise oxytocin levels, but decided to google anyway, and voila: Oxytocin and the Biopsychology of Performance in Team Sports, Gert-Jan Pepping and Erik J. Timmermans.
