Did the man shoot himself against his will?
Hmm, not sure what to do now, as there can be any amount of reasons that would cause a sane and healthy man to shoot himself just by looking at something, and that's just when it's assumed he is in the safety of his own home.
Only for now, let me give you some advice as to how you might want to work your way towards the truth:These riddles almost never represent something that happens every day. As it is, you should assume that there is something special about the man in question and the situation surrounding him as well.
Was the man in the safety of his own home when he shot himself?
Is there any other window that the man could have looked through, or was this one the only one? Specifically, "other window" signifies a window that would let the man see something else entirely; a second window next to the original one that faces the same thing would not count.
The man was a burglar/thief. He looked outside the window and saw the police had caught him. Suicide was his only solution.
Was the person outside alive?
Was the person outside female?
The man looked outside, saw zombie(s) and killed himself
Doesn't this violate the non-supernatural law?
Depends, did this man correctly believe that zombies exist?
Awww, I was hoping to conclude the case with the claim that it was either Koishi hax or Flandre being her psychotic self that freaked the guy into suicide.....
What about my questions?
The man got in a fight and accidentally pushed his opponent out of the window, which was high up. His opponent died from the fall. Seeing this, the man committed suicide from shock/guilt.
was the death of the person outside caused by events or objects also outside?
Was the person outside ever alive to begin with?
The man is not in a movable container (i.e. not a vehicle)What is outside would not directly cause him harm (Yes answer to safety of the home question)The place he was in is not his ownThere are other ways in and out besides the window, though none of which are in reach without moving
Is the man in prison?
Did the man have any relation whatsoever to the events that lead to the death of the person outside?
Did he have any relation with the victim?
Is this event contemporary?
Was suicide the man's only rational solution to what he saw outside?
This is a weird guess, and probably wrong, but:the man shot himself because he saw, or thought he saw the ghost of a person he killed?
Was the man of a sane mind?
