The way I view lightworking is not love vs. fear; it's whether I do what I do primarily for MY benefit, or for the benefit of others. I choose to do my work to benefit others - of course, I receive benefit as well, but that's not my primary purpose. My purpose is for *what I believe* is the greater good.
In your scenario, I would kick some ass with love!
Lightworking doesn't mean I
never act for my benefit, or the benefit of those I love. It's an overall view that shapes my intention.
