Some castes don't consume meat because of some religious traditions and practices. But knowingly or unknowingly we all have killed insects.
For example, even microorganisms that enables curd from milk which we consume. So, indirectly we all have consumed non-veg.
Even plants also have lives in which we are taking it.
And night times, we definitely kill mosquitoes or bed bugs by spray/liquid or hands.
And during the walk, we may have stamped on ants as well.
So, will we go to hell? Is it a serious crime?
