Not true. There will still be people who are weak, who have a natural inkling for self-preservation. On the otherhand, there will be people who will absolutely worship you for having all the money in the world. Some won't care. And only a number of them would be altruistic enough to see the dark side in you and try, just try to eliminate you. It will depend on you, however, if they would succeed.

Over your own happiness, yes.

I wish you luck on the endeavor. I on the other hand, find it to be a futile attempt. Many have tried, all have failed.
