I should save my game in a whole new slot
Then you're not role-playing. You're participating in a power fantasy.I dislike being boxed in.
A good RPG is capable of locking away certain options and paths based on the type of character one role-plays but still provides the option to re-open those paths if one dedicates themselves to learning the appropriate skills. The open approach of Skyrim and Fallout 4 have been criticised frequently that one can see that there is an negative trend being practised by Bethesda.
An example of such a good RPG is The Age of Decadence, a game where your chosen role is capable of unlocking and locking away options not suited to your chosen role i.e if you play a Grifter, you will rely more on your grifting skills than your combat skills to handle situations etc.:
