Guts has some toxic, destructive traits too.
There seem to be almost no healthy human relationships in this series.
As of now it seems as if the entire story is mostly about revenge.
The violence imo has a lot of (body)horror elements which makes it less realistic and at the same time more easily to digest. It's rather disgusting and gross than gory.
When I compare it to Vagabond the depiction of violence is very different. There it's more realistic and you actually feel more attached to the victims.
Berserk seems more like a huge surreal nightmare.
