NO THEY DON'T.
Think of it this way it is not like your mom would kill you.
Actually, yes they do. Boar bears (male bears) have been known to actively go about and kill young cubs if they are not watched by their mother or if the mother has been scared off or beaten so badly that she can no longer defend them.
Males do not aid in the rearing of cubs, in fact they may kill them.
Occasionally, males will kill young cubs, especially if they are unprotected.
No.
They kill peopleThey kill other polar bears, including cubs.
Males will sometimes kill and consume cubs.
The female polar bear lives with her cubs for more than two years. By that time they are weaned and have learned how to hunt and look after themselves. The male polar bear does not live with them. In fact, male polar bears have been known to kill cubs.

Mommy Black and Grizzly bears have to protect her cubs from other bears. This does not require that it be tough times. Bears are opportunistic predator's, meaning if they can kill it easily they will eat it, and they don't care what meat it is.
No, unfortunately they do not. A grizz or for that matter another black bear, may even kill the cubs if they go near the adult bears. It is not called "the wild" for no reason.
Male bears have no role in the rearing of cubs. In fact, male bears may kill the young if left unprotected.
Surprisingly, bears are usually scared of humans. Mother bears are cautious to protect their cubs from male bears, who will kill cubs if given the chance. Besides that, I don't think that bears are afraid of other animals, though they obviously are careful about hazards in the landscape (for example, cliffs).
Humans are about the only thing that kill adult black bears. Sometimes cubs are killed by cougars and other bears.
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
they we start mating and have cubs they will start hunting and they will start protecting there cubs and they will not be afraid to kill or attack any thing or ant one
