What would you do if you were in Daniel's position?

[Smithens]

I'd feel I'd owe it to my former self to seek out this Alexander fellow and murder him.

Once I reach the wine cellar I would start to reconsider my quest.
Once I see my first monster I would seriously reconsider my quest.
Once I escape the water area I would start to consider suicide.
Once I enter the storage room I would seriously consider suicide.
Once and if I reach the prison, my mind would be too far-gone to care anymore.
