The predator does not kill children or pregnant women. Predator 2 showed that. A kid with a toy UZI spotted the predator with his light bending and as a precaution the predator armed his shoulder cannon, but upon sensing it was not a real gun he disarmed it.
Also the subway showed he found a fetus developing in a woman and immediately released her.
No, but you would be an unarmed helpless guy. Not sporting enough for a predator. Or at least you will fake being helpless! There is no honor in slaughter.
