I've seen in another thread a number of people who had good reason to not wish to see excessive fake violence
The problem is that the game does involve excessive fake violence, and it is not limited to simply blood.
There are scenes of people being decapitated so simply not taking the One Handed perk for it wont solve that.
Finishing moves can be rather brutal and aren't simply limited to the play, NPCs can perform finishing moves too.
There are no doubt countless examples besides these too, that I unfortunately cannot list as I do not have the game.
The game involves excessive violence. If your constitution cannot handle excessive violence then do not play games in which excessive violence is a major player.
