Not not to mean but I believe cockroaches, centipedes, other venomous crawlies, jellyfishes (sea wasp box jellyfish, Portuguese man o’ war, etc) , Asian giant hornet and a couple other creatures have no purpose of existing.
To me any creature that's very disgusting, can make you feel sick, pass out diseases or kill you has no reason to be here on earth.
It's just those on the list that I really find disgusting.

no. biologically, all animals have a place in maintaining the functionality of the food chain. when one species goes extinct, it creates a gap, and it takes a lot of time for other species to adapt and fill that gap, if they can.0
