What is the point in killing people?

many many reasons some because the animal is ill and in pain and they cant do any thing .second there just mean and hate animals. third there hungry like i know a soldier that had to eat a dog or starve to death. and reason that i cantexplain why would a YOU kill a animal just ask your self that.People need to eat animals its a source of food's meat .Its no neceseraly that all people hate animals it just that we need them to eat.Although some people kill them to make fur,which is not good,lately some people have been killing them to get tapeworms and sell them for thousands of dollars.There is no right or wrong to this question we use them for many reasons some are not very nice but everyone has there own prospective on this one. The effects of killing animals are they could become extinct which is not good because we want the following generations to have know this type of animal.
