Why is that an amazing feat lmao? Unless he had to defend himself of course.

If someone told me he was randomly fighting a bear and he killed it with a knife , I’d ask what the fuck is wrong with him for killing a random animal. Leave those bears alone you wanker.

Edit: if I found the story you are mentioning, he did seem to do this in self defense. Which is a shame, but he had no other choice it seems.
