You're jumping to alot of conclusions there...think of being clubbed, blunt force trauma to the head would be so quick that they most likely feel nothing, by the time the information is processed and the pain would be felt, they are already dead. And shooting is not a painless death either, if the shot was placed badly (not a head/vital organ hit)they would suffer before possibly bleeding to death or dying from shock. Don't be so quick to judge, it's the cycle man. Populations must have something controlling them, otherwise they would get too large and then they would be dying from starvation because the food supply wouldn't be able to support the number, and that's a far worse death than shooting or clubbing.
