If you kill someone who was going to kill millions of people ok

In my closing argument, i would like to show you, Furiousjay48, that how you could still go to heaven by killing another human being, although my intention is not that you go and start killing people but it is for your information. My son according to Jesus the messiah, he was so none violent that he preached that if someone slaps you on one cheek, you should turn your face and offer him to slap on your second cheek..... The quran says killing one person is as though you have killed all of mankind...... with this said, there are situations where you might be forced to kill the person and still go to heaven...... First situation is that you kill a person in self-defense, e.g, you are at home and a robber attacks you there and you resists, and he threatens to kill you so you and in the struggle you end up killing him another example is that someone tries to kill you by shooting you with a gun but you end up killing him to protect yourself..... Another situation can be that you see a man trying to rape a women and you intervene and try to stop him but the person attacks you and you end up killing him. Another situation is that you are in the law enforcement agency and you kill a person while upholding the law in the line of duty.... Another situation is that you kill the person who killed your blood family meaning brother, sister, mother and father, wife and children, if you know who has killed your family member or members, God allows you to take revenge and kill the person responsible for the heinous crime. Lastly, God allows a person to ascend to heavens who fights for God's religion and kills God's enemies. Mind you i am not talking about the wars based on nationalism e.g WW1 or WW2 or Vietnam war or war on terror currently imposed by these nationalistic governments. But rather i am talking about religious wars like the one between David the prophet of God and Goliath. A fight solely based on Abraham's religion, to make the commands of the God of Abraham, Moses, Jesus and Muhammad prevail, a fight without which its survival will be difficult. So i am ending here by answering your question which you posed in the start of this debate......... Furiousjay48, my dear son, read all the gospels and read the psalms, the old testament( Torah) and the quran and only then after you have read all of those books yourself without any other person's influence and guidance but rather read all these books with the belief that God will guide you and give you knowledge, only then after reading them you will realize all these books are from the same God, the God of Abraham and its the same message of love, peace and then you will come to the conclusion all these divisions between people today is because in truth they haven't read all these books and they are in reality not following them, for its the same message from the same God. The first book was revealed to Moses, the Torah giving detailed laws according to the needs of that time period, after centuries passed and time for extension came and God sent another messenger named David and revealed Psalms to him giving guidance and laws according to the needs of that era and then centuries passed then the time for further modification came and God sent another messenger name Jesus son of Mary and revealed the Gospel to him according to the needs and laws for the people according to the requirement at that time and then in the end 600 years after Jesus, came Muhammad with the last book of the same God, the quran.......... It has been 1400 years since Muhammad's death and no prophet has come because the chain of messengers has ended because the message is complete...... May God bless you my child and i hope God, the loving one always bless you with health, happiness and all good things of life which God has allowed us to do...... Love and sincerely yours Omer.
