I enjoy watching my centipede chase down and eat insects alive
Do the bugs get hurt while you are watching?
Yes. The centipede devoured some of the insects alive
Your centipede needs to eat, and this is what would be happening in nature.  However, it is a bit worrisome that you take so much pleasure from watching this happen.  Maybe you could set the animal free and get a new hobby?
I don't like you threatening me with your morals.
I am not trying to threaten, but I do find it a bit concerning that the plight of small animals is a source of pleasure for you.  If you are only interested in this from a scientific standpoint, then that is fine, though.
