i stop the game in skyrim cause i personally did not like what i did

Just something i wanted to post as i talk about in class the other day and i thought there is some relevance to it.

Recently i was back playing skyrim and in between traveling to a quest i was attacked by a drunk nord so i in turn engaged him during the fight i thought it was strange that he was using his fist while i had  my battleaxe and before i finished question this i killed him after a few hits with my axe upon then searching his body i discovered he did not have a weapon on him at all

as i walked away i felt really guilty as i fought him with a weapon while he was drunk and did not know his actions and if i just fought him off with my fists then he would still be alive and so i felt a bit of my moral code flowing into my character in the game and i actual stop the game and return to an early version before i killed the drunken Nord

Hoping i could rectify what i just did but when i traveled the same route i was attacked again but this time a thief attacked me with a weapon trying to steal my gold which i fought off  and killed but i felt justified in that killing than i did when killing the drunken nord

the reason for posting it for some they might of not cared about there actions cause it is a virtual world for me thou as playing this character in this world  in my head have gave some of the same morals that i have and although it is a virtual world i believe that my character would not react in that manor against an unarmed man.

i thought it was interesting giving the previous discussing in class that it's just pixels and the virtual space why have those feeling for a character that does not exist but what if you make this attachment and in your own mind is a representation of yourself in this virtual space?
