According to
Christianity, Satan was originally an angel who rebelled against
God (power to the people!) and also influenced Adam and
Eve to eat the fruit of knowledge- which implies that had they of not eaten it, then we might not have possessed the knowledge to question authority. Ultimately, Satan was thrown into the lake of
fire with his other followers- which also implies that Satan is a victim too in all of this, and considering he braved
god's wrath to question the lord's divine authority- it says a lot about how Satan should be perceived, and that Satan might have had decent intentions after all. Of course, this is all subject to whether you have religious ideals- in which case, you might want to consider which being you're supporting :P
Satan's ultimate goal is to lead people away from the love of
God, and to lead them into fallacies which
God opposes- or if you look at it another way, fallacies which mean God no longer has control over you- some of these fallacies are listed below:
Premarital
sex: A normal desire for human beings, and it should not be perceived as a sinful. Everyone has the right to love their body and the body of others, providing they realise what
sex entails and that they are aware of any implications that follow the activities they are parcitipating in.
Drugs: As we know, some drugs are very dangerous for the body and mind- but naturally occuring drugs such as weed and hallucinogens can lead to experiencing alternative perceptions of reality, and providing necessary precautions are taken, this can lead to positive realisations about yourself and the world you live in. And
may also result in a more independent mindset- which would be bad for
God, understandably...
Rock
Music: Opposed by hardcore Christians, Rock
music is actually celebratory of everything that makes
us human- and is known for championing complex ideas (seen in art rock, etcetera) and anti- authority ideals. Again, bad for
God...
In all, there are lots of things perceived as sinful by
Christianity- most of these are merely aspects which contribute to our independence and rights as a human being.
