Without emotions, life would be pretty much boring and colorless, in my humble opinion. Pain is probably the opposite of bliss and without it, we wouldn't be able to see the opposite, I am afraid.
Our creating and destroying impulses are normal, I believe. In order to build something new, the old one must be destroyed sometimes, so there is enough room for the new stuff, right.
Just human nature...
Excellent material, as usual, pleasure to read!
