Who's ready to cry?! Show of hands

You've seen Knight Hero, now get ready for: RGB but a lot more sad, somehow (O_O;)

Spoilers for "The Warfstache Automated Interview Automaton" and "Who Killed Markiplier"

Okay, so, I just watched The WAIA with my brother, and at this moment I'm watching WKM with him. Then in both voices afterward, the audio of Wilford said that the robot is "a scan of my own noggin". So, based on that statement, everything the automaton says reflects Wilford's genuine thoughts and memories. Going off of this, the shocker comes in the second to last video. In that video, the automaton described the party during WKM, and then said "I didn't know the gun was loaded. Is it my fault?" This suggests that Wilford was the one who killed Mark, but upon watching WKM again, the detective stated that Mark was "Stabbed 37 times, poisoned, strangled, and shot, in that order." The automaton never mentioned anything about the previous 3 actions, only that he shot Mark. This could have been an accident, due to their game of Russian Roulette, the "dangerous game" that he also mentioned. It is possible that Mark was one of the victims that Wilford DIDN'T kill, but instead thought he was to blame. Guns have been known to rarely fire without pulling the trigger. So if you're eccentric Wilford, you would wave the gun around like it's no tomorrow, because it's not loaded. Except it was. While in his incapacitated state from the party, he could have seen Mark passed out like in their university days, not realizing he was already dead. He could have tried to keep the party going, until the gun fired. Now, I'm not the most caught up with Markiplier lore, but I think that there are some more angles to consider in Mark's death.....
