Quran:the final solution?

Quran came out when there was violence and there were corruption.It is last most holy book after tora,Bible etc. Everything is explained very detailed in Quran.So is this the final solution to everything? Possibly one of the greatest misconceptions about Islam today is that it is a violent religion whose followers support acts of terrorism. While in reality terrorism and violence entirely contradict the teachings of Islam. Islam is a peaceful religion based on mercy and principles. The Quran encourages people to ameliorate their relationship with God and with the people around them through good character and acts of good deeds. It states in the Quran “if anyone kills a person – unless in retribution for murder or spreading corruption in the land – it is as if he kills all mankind, while if any saves a life it is as if he saves the lives of all mankind.” Many view this in a very literal sense and view this as Islam condoning death penalty for corruption. But in my view it seems to me here the Quran is against the killing of innocent lives and God is reminding Muslims the sacredness of human life and also teaching the other faith communities before them. Growing up in a Muslim family I grew up believing in Islam as a religion of peace, and I for one believe this statement from the Quran can be interpreted in many ways, just a matter of fact of how one interprets it.
