Well, it is not like saving regularly is very complicated - I hit F5 every 5 minutes (and the saving process takes maybe 2-3 seconds) and I already have >150 hard saves (although I am not even close to finishing the game)... Beside, grave digging IS dangerous and an immoral task. I remember the one grave in Cyseal, where characters even discuss whether they should dig it up or leave the dead rest in peace (and there is even a warning "are you really sure you want to dig it up?")
