In The Bible, in the Book of James Chapter 1 we find a very important truth, for there we read:vs 12- "Happy is the man that keeps on enduring trial, because on becoming approved he will receive the crown of life, which Jehovah promised to those who continue loving him. When under trial, let no one say: I am being tried by God. For with evil things God cannot be tried nor does he himself try anyone. But each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin; in turn, sin, when it has been accomplished, brings forth death. Do not be misled, my beloved brothers. Every good gift and every perfect present is from above, for it comes down from the Father of the [celestial] lights". Yes, with evil things, god does not try us. God does not cause suffering. He is not responsible for the wars, the crimes, the oppression, or even the natural disasters that cause people to suffer. The Bible teaches that "he cares for you". (1 Peter 5:7) God hates wickedness and the suffering it causes far more than any human does. (Isaiah 55:8, 9) The Bible clearly states: "The whole world is lying in the power of the wicked one." (1 John 5:19) When you think about it, does that not make sense? This world reflects the personality of the invisible spirit creature who is "misleading the entire inhabited earth." (Revelation 12:9) Satan is hateful, deceptive, and cruel. So the world, under his influence, is full of hatred, deceit, and cruelty. That is one reason why there is so much suffering. A second reason why there is so much suffering is that mankind has been imperfect and sinful ever since the rebellion in the garden of Eden. Sinful humans tend to struggle for dominance, and this results in wars, oppression, and suffering. (Ecclesiastes 4:1; 8:9) A third reason for suffering is "time and unforeseen occurrence." (Ecclesiastes 9:11) In a world without Jehovah as a protective Ruler, people may suffer because they happen to be in the wrong place at the wrong time, such as in the tsunami that you mention, or like on 9/11. God does not cause such suffering. He allows it to happen. He has given his son to us to die for our sins. Shortly, His son will end this wicked system that man has erected on the earth, and establish His Kingdom fully. At that time, all suffering will cease.
