Please Calm Down
your making me sad.
You shouldn't think of your self as a monster, don't be silly, your normal and it is completely natural for the bee to die.
You see, all of the bee's digestive system is attached to the stinger, forming one big organ, and once the stinger breaks off them, their digestive track goes out with the stinger, they die a quick death. You did the bee a bit of a favor, she could have died a very slow and painful death if it wasn't for you!
Now, wipe those tears and smile, ok?
