God has given us the faculty of learning, reasoning and decision making. All other creations do not possess these faculties and hence are not answerable for their acts. A lion is not sentenced to death for killing a man. It is a part of its natural programming. We are answerable for our acts because we choose what we deem right. We cannot blame the Almighty for this as He has given us the guidance on which we should base our decisions and choices.There was no point in creating us if there was no afterlife in which we could be judged. That is where the purpose of life comes in. The Quran wants us to develop our personality and character in the light of its values.A lot of people in the West and other places commit suicides because they do not see any purpose in life.Their materialistic concept of the purpose of life makes them see no further than this world.Their purpose of life ends when they achieve worldly success.
