Why would the merciful Almighty put human being in hell-Dr. Bilal Philips

In Saheeh Muslim it is narrated from Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: “Allah has one hundred parts of mercy, of which He sent down one between the jinn, mankind, the animals and the insects, by means of which they are compassionate and merciful to one another, and by means of which wild animals are kind to their offspring. And Allah has kept back ninety-nine parts of mercy with which to be merciful to His slaves of the Day of Resurrection.” (Muslim, al-Tawbah, 6908)
