Nice post, as usual. I was actually eagerly waiting for my weekly psychology dose :)
I have always acted differently when doing something wrong or. I actually do not see any need for feeling guilty. Things have been done. Period. They are my responsibility. Period too. Now, from there, instead of feeling this or that or even having to suffer, I think it is better to move on and see how things can be fixed. I am happy to see that this more or less matches the detective way that you proposed.
