They are naturally aggressive to other male bears when they encounter each other, although polar bears are free ranging and don't establish and mark territory. They will attack and kill the cubs of another male so that they can then mate with the female. They will fight with the female as she tries to protect the cubs, although not usually to the death. Other times, although rare, it may be because they are starving.

polar bears kill other polar bears to demand their territory and because of male stress
