Questions: Religion & Spirituality

So if you 10 years your duty was to be Satan, what would you do and how would you go about in doing it.

Please explain your answer deeply and thoroughly. Go into exact details about how you would use your powers to try to deceive atheists into thinking they have nothing to fear, about convincing people there is no God, about insisting they kill themselves or whatever it is.

Please give a timeframe you would do it in too. Like if some things you'd do the first 5 years and other things the final 5 years and how you would set this up.

Apostasy or the worship of a false idol is a something all religions are against. In order to call for a holy war against anyone, one must be the Calif according to the Quran. Those in the Muslim faith committing apostasy by saying they are superior to the Calif by calling for war have also committed huddud against Allah by over stepping boundaries reserved only for the Calif. These are directly taken from the Quran and no latter teachings.

Also what of charity? Is it not a pilar of Islam to grant charity against those who have wronged you in a pursuit of their own goals? All though Qisis allows for equal retribution by the victims or their heirs, charity, a pillar of Islam, requires you to seek a lesser form of justice. Are those of the Muslim faith that call for a Holy war against anyone abandoning their core beliefs in the 5 pillars of Islam?

As a man not of the Muslim faith I may be missing something glaringly obvious. Which parts of these questions are not supported by the Quran? Why is Allah not the Islamic word for the English word God? Why have the powers that be used apostasy to justify the abandonment of charity? If you are a man of the Muslim faith, please consider me a student of your fiqh to educate me on my misconceptions.
