If you wouldn't be condemned to hell for living an honest, altruistic life then why bother with anything else?
It’s a little bit deeper than just being a good to one another, and I think the hell and heaven thing gets people to ask the wrong questions. I am a student of the Sufi school; which is the spiritual order of Islam (or Islamic mysticism if you will) and the purpose of it is to
strive towards curing the illnesses of the human condition and development of a higher form of perception. Our spirits are little pieces of the divine and worldly existence is disunion (or severance) from the Great Spirit that is Allah, and the life to come is reunion.
I’ll share a story I quite like that’s in relation to the bolded bit:
City of Storms
Once upon a time there was a city. It was very much like any other city, except it was almost permanently enveloped in storms.
The people who lived in it loved their city. They had of course, adjusted to its’ climate. Living amid storms meant they did not notice thunder, lightning and rain most of the time.
If anyone pointed out the climate, they thought he was being rude or boring. After all, having storms was what life was like, wasn’t it? Life went on like this for many centuries.
This would have been all very well, but for one thing: the people had not made a complete adaptation to a storm-climate. The result was that they were afraid, unsettled and frequently agitated.
Since they had never seen any other kind of place in living memory, cities or countries without some storms belonged to folklore or the babbling of lunatics.
There were two tried recipes which caused them to forget, for a time, their tensions: to make changes and to obsess themselves with what they had. At any given moment in their history, some sections of the population would have their attention fixed on change, and others on possession of some kind. The unhappy ones would only be those who were doing neither.
Rained poured down, but nobody did anything about it because it was not a recognised problem. Wetness was a problem, but nobody connected it with rain. Lightning started fires, which were a problem, but these were regarded as individual events without consistent cause.

“The ordinary man is said to suffer from confusion or ‘sleep’ because of his tendency to use his customary thought patterns and perception to try to understand the meaning of his life and fulfilment. Consequently, his experience of reality is constricted, and dangerously so because he tends to be unaware of it. Sufis assert that the awakening of man’s latent perceptual capacity is not only crucial for his happiness but is the principal goal of his current phase of existence - it is man’s evolutionary task.”
I highly recommend (for those who are interested) to read the works and poetries of Sufi masters like Jalāl ad-Dīn Muhammad Rūmī. Beautiful stuff.
