To answer you Lopt, the devil did not permanently exist, God created the angels as worshippers with limited free-will. The highest of angels, Lucifer who was the lead angel of worship, saw himself as being greater than God and decided to lead the angels in a rebellion against God. God smote them down and cursed them, after a third of the angels had fallen. Afterwards, God created Earth and with it, all that exists in our universe. Then he created man along with all of the animals and placed them in the Garden of Eden. But man betrayed God just as the angels did and he cast us out of the Garden. God is a just God, truly capable of great love. He would only smite you down if it had another purpose such as: proving to people His power. He does love all people and defines love, but when a person or group of people go on long enough while they choose to reject him and blatantly defile that which is holy, he may destroy them. For we do not deserve to even live on this planet that he has granted us so gracefully. And because he is a just God, he shall do what is neccessary to preserve justice and those who are to be harmed by the rejection of God's love. Just as he did with said tsunami.
