Do we really need to sink ships?

I mean, it's a beautiful game, the ocean, the underwater, the sky, the sunset, all those mods..its all beautiful.
I think most of us are playing sh5 just for that.
But personally...if i was a captain in WW2 of a german sub. I would rather sail of to some beach and enjoy a swim and a beauty of waves and nature.
I wish someone made a mod where i can go and swim rather than hunting and sinking ships, all those good ships...why?
We all know how nazis end up, do we really want to end up the same with this game?
