Is Islamic Slaughtering Cruel to Animals?

Yep, just like everything else they seem to try to inflict as much pain as possible before killing something

No. Besides that, by slaughtering the animal, it'll prevent you from the viruses in the animal blood. Animal is the god creation. Only He knows what is good and what is bad for His creation.

i don't think so, because the God had already stated that this kind of slaughtering is prohibited and even suggested in Islamic great day "Idul Adha" while we are talking about something that has "prohibitation" from God I guess there is no matter about that 'cause He the one who created this world and made all kind of rules for us, creatures
