Why did all-powerful God murdered the Haitian people during the earthquake
Be careful what you say to God, the word "murderer" means something different, killing another person deliberately. Did you want to call God murderer?
John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
God is the owner of life, he have the right to take it or give it
John 10:17-18 Therefore doth my Father love me, because I lay down my life, that I might take it again.
No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
There are so much ways to take life it can be in a lightning way, by earthquake or any other natural means, he own our life and can take it anyhow he want it
Hebrews 9:27 And as it is appointed unto men once to die, but after this the judgment:
Satan and his convoy is the murderer, God cannot be called
Ecclesiastes 8:8 There is no man that hath power over the spirit to retain the spirit; neither hath he power in the day of death: and there is no discharge in that war; neither shall wickedness deliver those that are given to it.
Death is beyond man's power, it is only God that can kill and let live
Job 12:10 In whose hand is the soul of every living thing, and the breath of all mankind.
