A person can't make It happen so he acts as a shark and moves without remorse, though a mere ten second's contemplation and emotional, intellectual understanding of the things he, without sorrow, ignites in his wake, would be enough to force his hand to tie that well deserved noose and slip it around his slimy neck and hang himself dead. He, much like a snake, is deaf to the screams of those he has bitten, and blind to the ruin behind him. His one track mind - his selfish mind - which blocks out all that his nature doesn't wish for him to acknowledge - does for him what is convenient for him. Eliminates the reality for him. That is his nature's wish.
