Whether we choose to think about it or not, humans in their daily lives directly cause immense suffering to the little creatures. Leaving them half crushed, spraying poison, drowning. Have you ever observed these events closely, and possibly worsening the situation for the insect: tear off a leg, peel a wing?
There is no pleasure in witnessing suffering of even insects. There is only acknowledgement. The point is that I think people should pay attention to insects more but not feel bad/or even care when they die.
