Why is Iago most responsible for the tragic events of Othello?please give me list reasons why!

Iago is most responsible for the tragic events of the play
because he poisons Othello with words. Of course, it is Othello who commits the misdeeds
but it is Iago which propels him to do so.

Had Iago not
laid so many "traps" for Othello, he would have simply continued to live life as he had.
Iago thrusts him into a jealous, murderous rage and is therefore the most responsible
for the events of the play.

One could argue that Othello
should have kept himself in line and not resorted to violence, but one must sometimes
blame the person who lights the dynamite, not the dynamite
itself.
