According to me ,this is the most sinful act that people are doing.To take lives of some innocent people will never make a country or a group of people great .Please don't hear what others want you to understand rather think by yourself ,about that God to whom you believe ,your family and then think whether they had done the same thing as you are going to do.May that God said to protect ur people but not by taking others lives.So before doing this see all loves around you and then come to that place and see whether same things prevail there.If you agree then what is difference between your and that place.And you know you will get the same things.See God never made these differences we people did it then its now our duty to walk on His path not on the people made path.After this I would like to say ,hearing or reading this ,read your religion holy book by yourself,and find by yourself your wrong ,surely you will find it.
