backup your saves.
if your character dies, the save file is erased - if you backed up your file before, you can just copy it into the saves folder and keep on playing.
I wouldn't call it normal saves. It is definitely not friendly way to experiment in many (lots of) ways.
Save scumming is metagaming. If you want to metagaming use external methods.
Then playing again and again from start is metagaming as well...
And I mean not save scumming (like reverting bad consequences), but making learn-ahead time point and returning to it as many times as you need to learn variants of doing something (not outcomes!).
