People should be educated

We had a long vacation because of bayram and lots of Muslims killed animals in bad condition.I am sorry they just sacrificed an animal for God. This is region and of cource they need to do it,but people have to be careful. People have to know cows,sheeps or steers are alive and they have a life,we cannot damage them. If they are sacrificed for God, the slaughter should be healthy and without pain. We watch television and we see how animals kill in bad condition and it really looks disgusting.I don't understand how people eat this meat?
