Nope. I have no control over what others do, only what I do and what affects me. Some things tug at my heart strings, others don't. I never said there's anything logical about empathizing with a bug. My compassion is obviously selective and limited, but at least it exists to some degree and that gives the motivation to make improvements for all life.The ladybug had clearly come to it's own end, and by saving it's life you will cause hundreds more deaths because the ladybug will go on to eat many, many aphids. Gobble them up alive.
Any guilt there?
Look at what Temple Grandin did to help create the improvements of slaughterhouses. Why is it wrong to care enough to want to see and put effort into advancements? It's not.
