I believe there's no “Heaven” or “Hell”, it is only what will remain in our essence that will decide how chaotic our futur will be…
The sins are only a concept made to “balance” a civilisation.
“Lust” was made to protect life and its values. In the past, contraception wasn't very popular; many life ended in misery. And how many love affairs are still taking a wrong turn today. There's no problem in having fun, but we must take our responsability and respect our relationship.
“Gluttony” was made to keep a balance in everything that we consume; now, we're taking everything from mother nature, and the weather is falling on us.
“Greed” was made to keep us from destroying another “social shelter” by taking what someone else has or by keeping everything for ourself in spite the social needs.
“Sloth” was made to push people at develloping their values, to add what they can in life.
“Wrath”, well, like we say “Stay cool, overreacting won't lead you anywhere” :p :-)
“Envy”, let's say it's better to enjoy life and devellop our own qualities… than begging what someone else has or lose ourself in negatives actions.
“Pride”, it's normal to be proud of our actions, but to think “I'm special”… give me a break.
These rules were made to create the “civilisation”; a structured place where everyone can find some security and happyness, when everyone is working for this objective. These sins, to my view, have nothing “deadly”; but negative actions lead to negative results. But, in the “young ages”, let's not forget, the law of the sword was also the leading authority.
Today we have everything. Our technologies and ressources are soo big that we have ignored its limits. Depending where we are on Earth, the civilisation is better than what it was in the dark age. But we are now forgetting why it is so important to respect and understand our similars. Our moral values (not religion) are not teach in schools or the media. We don't need to speak about God, Jesus, or the Holy Grail, we need to speak about the values a person has/can develop and what a person can accomplish, how our biology influences our behaviour, and, of course, learn how to work for humanity and not money.
Like Ozzy said:
“Your higher power may be God or jesus christ
It doesnt really matter much to me
Without each others help there aint no hope for us
I'm living in a dream, a fantasy”
