Question

Why did The Undertaker at Summerslam throw the ladder out of the ring? Was he angry at himself?

Answer 1

That's probably why Taker took his temper  out on the ladder.He figured he maybe should have beaten Edge quicker or easier than he did.It was a hard fought match that left The Deadman beat up and bleeding with him barely able to stand.The cage match is Taker's territory and he figured he should have won the match more easily.

Answer 2

HE was frustrated at himself.

Answer 3

i 'm guessing the ladder was in his way lol
