Is God to be blamed when bad things happen to us individually or on a global scale. Please read the explanation below given by Srila Prabhupada.
Na kartṛtvaṁ na karmāṇi lokasya sṛjati prabhuḥ
Nor does the Supreme Lord assume anyone's sinful or pious activities. Embodied beings, however, are bewildered because of the ignorance which covers their real knowledge - BG 5.14
Now you can ask that "If Kṛṣṇa is giving sanction, then He is responsible for my bad work also. Good work, of course, He is responsible. So bad work He is also responsible." Now, here the answer is na kartṛtvaṁ na karmāṇi lokasya sṛjati prabhuḥ. Prabhu. Prabhu means the Lord. The Lord does not create work for you, neither He creates the result for you. Na karma-phala-saṁyogaṁ svabhāvas tu pravartate. Svabhāvas tu pravartate. As you have acquired your characteristics, so you create your own work and you create your result of own work and you become entangled. It is not the creation of God. You create. "How I create? If it is sanctioned, if it is controlled by God, then how I create?" The question may be. Yes. The answer is very simple.
You can understand that a person who is criminal, who is condemned. Now he's condemned to death or he is condemned to be imprisoned. Now he makes appeal that "Oh, excuse me, what was done(?)." But the judge puts him into the jail or condemns to life. So he thinks that "The judge has condemned me to death or the, he has put me into jail." But is the judge enemy of a particular person that he puts somebody into the jail and condemns to death? No. I have created. I have created my jail life before. The judge is simply giving me the direction. "Oh, you have done this. Now you have to go." He is not responsible. Similarly God is not responsible for my work, neither He creates my work. It is my nature, it is my characteristic, which, by which I create my work, I create the result and I suffer. God simply gives direction because He is the supreme director.
So He is not responsible. I am responsible. I am responsible. But if I become Kṛṣṇa consciousness, if I act on His account and completely becoming dependent on Him then He is responsible for everything happening. That is the principle.
