Is it bad when an insect kills someone?

Some insects are very poisonous.

Nature red in tooth and claw...Kipling.

I think this depends on your beliefs. To a Buddhist, killing a flea is bad karma. To most other people, its not an issue.

Everything living is conscious.

And around and around we go.

My home is infested with ants. Should I spare the ants and not be able to live here, or call the exterminator to commit mass murder?

Common sense says I'll make the call.
