No it doesn't bother me.
Death is something that children should learn and whilst we shouldn't sugarcoat the fact that death happens, we should also prepare children for the inevitability of what death is about.
To tell you the truth when I was a child, I had some understanding of what death is by the courtesy of disney (Bambi's mum, Mufasa) and Don Bluth's Land before time (when Littlefoot's mother died). These were all very sad but it is a good thing to learn about these life experiences.
Although perhaps it's not one of the best ideas to through one's brother of a cliff face to achieve that.
