Who had the more tragic death of there Parent/Guardian PP or BW?

Personally I feel that Peter Parker's Uncle Ben had much more of an impact on him than Bruce Wayne's parents dying. I dont believe Bruce was old enough to fully understand the real impact that it supposedly caused and made him The Batman. Peter Parker on the other hand was a high school teenager and ultimately it was HIS fault that Uncle Ben was killed. I believe that fueled his fire. Bruce on the other hand was 8 years old.
