cliff of guilt

Do I thank my lucky stars for spiders because they keep the insects off of me? Sure, but how often do I thank them for this unbelievable service? Where’s this going? Is it over the cliff of guilt? Is it that if it’s not one thing, guilt is the other?

Is guilt a good thing? Is guilt part of our make up because if we couldn’t feel guilty, the earth would be a very different place and perhaps we humans wouldn’t even now exist?
