It doesn't matter anymore because what happend, happend. before my whortless nephew was born, I was still close becoming king if something happend to Mufassa, but Simba's birth completely cut me out from the king's election, and this is when I decided to kill them both. and quess what, I ALMOST succeeded...
What would you have done if Mufassa survived the dropp and later confronts you for trying to plot against him? I quess you would shiver out fear right?
