All food is cruel. You can, at most, minimize the cruelty.

But you should know that millions of insects are killed in agriculture. Insects are indeed animals.

You can, if you want, minimize the amount of animals your presence in this world brings to an early death. But you cannot reduce it to zero no even near zero. Probably hundreds of small animals (most insects but surely many other small animals) die each day because things you do.

The line on how much do you want to minimize might be on one place for you, and that's ok. But you have to respect other people lines as well.
