Ok so I just found out something new. Some of these Giants are not bad at all .

Have you ever heard about how Sasquatch guard portals ? I think there are beings that control a certain region and maintain dominion . If they are killed then the bad forces will take over and have dominion there.

There is a story I am trying to find where a yeti was killed in Afghanistan my the military and the locals week very angry and upset claiming that the giant was not bad .

Of course some of the Giants are bad and eat people however of you read this article it kind of exlaind things detail better
