We choose our impact. We can choose to impact the world for good or evil. It matters not whether your impact is to the positive, or to the negative. It is still impact. Every day we effect all of those we touch, for good, or ill. "To be or not to be", is not the question. The question is: We are! How should we live? THAT is our choice! I would argue that even when when we choose "not to be", that choice is futile, because it is not our choice at all. We did not place ourselves here, nor can we wipe ourselves from existence, neither in this life, nor the next.
