muslims a big monster who killed people?

how can you think that this is something wrong? it was done by prophet Abraham and Muhammad (PBUH) observed this tradition and he said that it washes away sins. and Allah Himself says that neither the blood nor the meat of the sacrificed animal reaches Him, but it is the devotion of the people that Allah sees and He forgives the sins. if you think that this is something wrong, it is your loss. but you don't have the right to say that this is wrong. this is the one of the two major festivals that our prophet observed, and the meat of the slaughtered animal is meant to be given to the poor and relatives and part of it can be consumed by self. just think how many families are fed... this is the opportunity even for those people who do not do charity, to make a difference for the poor people.
