I would rather worry about what are you doing to reflect the Christ of whose mystical body you are a member, rather than scolding the Almighty because you don’t see Him (a kind of blindness that should not surprise us, unless we had the pretension of thinking we actually could see - Jn 9:41).
I can tell you that surely the Lord is not in your sad, depressing (and, especially, useless) complaints. He certainly is in the hearts of those who are praying so that the evils of this world may be attenuated. Not that God can force man to behave against his own will, just like He is not forcing you to love Him with all your heart as He rightfully deserves. However by the suffering, sacrifices, penance and prayer of many, the Father often times dispenses extraordinary graces over the world, so that evil is attenuated in its disastrous consequences, tragedies are avoided or contained, and souls that would have fallen into everlasting fire may be granted special light to repent and be thus saved.
To seek truth? No. Your intention is that of an upset child screaming at his father. Be more humble, and if you truly suffer for those deaths, join those who trust in God and pray if nothing else is at reach. Pray for the victims, that they may enter everlasting peace in Christ. Pray for the survivors of this tragedy, that they may find the blessed hope that you, in the comfort of your home, seem to be on the point of losing. Pray for the men and women that are offering their time, abilities, and oftentimes their very life, to bring relief in such places. Pray for those who bring upon innocents such persecutions, for they do not know what they are doing. And pray to the Father for the sake of Christ’s sorrowful passion, that He may withhold His day of wrath against all evildoers.
You speak of misery, but I perceive you do not know the least of it. Which is good. I am glad for you. If you did know misery, you would also know hope, and you would most certainly know just where God is.
Do you want to seek the truth? Then kneel before a crucifix, and look into His eyes. Picture Him being savagely scourged at the pillar, He who is the innocent Lamb. Imagine how alone would the witnesses have felt, if watching the innocent Son of Man being so grievously hurt, they had exclaimed: “where is God?” Imagine how terribly empty the statement would be: “where was God while Christ was being scourged, crowned with thorns, and crucified?”
I apologize if I come across very blunt, but your “evidence for atheism” comes across as very hostile and deserves no patience and no kindness whatsoever. We are the church militant. We are called to pray and to suffer, trusting without hesitation in the lead of Christ and upholding without fear the faith of our fathers. We keep the light on. Others - those who cause corporal or spiritual suffering - turn the light off. You must be on one side or the other, as there is no in-between.
In Christo crucifixo.
