Why Jesus died??

Some atheists would begin with this same question. Why Jesus died? Why should a righteous man give himself to sinners? God's marvelous love is the answer for that. A love without comparison.
But this question I'm making as a Christian and to the Christian society. why Jesus died?
Many Christians will open up their mounths very proudly to say that Jesus died for "my" sins. Jesus died so that we might walk as he walked. Yeah. So we need to follow this and this rule, we must live in the Christian community, etc, etc. Obviously in one sense it is true. But isn't this answer incomplete? What was the final aim of Jesus' death??? Why we should consider it?
He died for all humanity.
Because Jesus's biggest commands were Love God over everything and love your brother as yourself.
Do the Christian community love the world? No, I'm not asking if they love the world schemes or the world view. I'm asking if they love the people there, the ones who are also affected by the perversity that pervades this world. Jesus taught us we should love not only the ones who are brothers or sisters, not only the ones we feel comfortable with. In this sense I have to confess. I always critized people for making acception of others. For being selfish. But I, myself, in many ways, am not so willing to deal with some people I think are too pround and conceited. But I have realized that they all need God. It's just appearance, nothing more. Just a mask that people wear to appear good. But inside we all have a big hole that can only be filled with the presence of Jesus.
It's a big difference to say we are Christians and be a real Christian. AS Christian we do not make aception of people. There is no rule of holiness that can forbid us to love people (if it is really love). People focus in biblical doctrines just like "can't do it", "don't make it", "don't say it", so that the bible must guide them exactly in what to do. An oracle. Unfortunately, if we read the bible this way we run the rist of trying to obey all the bible and letting the most important behind - love our neighbors. Isn't it not biblical? Didn't Jesus say it? So, why do people make so much war, why do they offend others, why do they fight and opress people because of what should be life???
Because they haven't find discovered yet the true meaning of Jesus' death. If we cannot see in people the blood of Jesus, then, it will be of no use. Jesus died for people. He died because God loved this world and gave his only son for it. Why should we complicate so much the gospel? God's work in real and powerful in human's soul. Why should we diminish the power of God and begin to imprision people in our rules and prejudices? God can do in people's live what they need him to do. Nothing less. We must love people first, and then, it will be a compliment to preach the gospel. That's a disaster when we try to follow one commandment without considering the most important one - love.
