Various scenarios: what would you do?

[robvalue]

This is a spinoff idea from various questions I've been putting to people. These are a bunch of hypothetical scenarios. Atheists and theists alike can answer. You may, for one reason or another, consider it to be an impossible scenario. If so, just pretend, and give the closest answer. Some of these you'll have seen before I'm sure :p

1) God appears to you. You are 100% sure this is the real, one true God.

A) He instructs you to kill your friends and family. He doesn't say why. Will you do it?

B) Christians: he is Allah. Yahweh is fictional. Allah is just as described in the Quran.
Non-christians: he is Yahweh. He is just as described in the bible.

Will you worship this God?

2) You have just replaced God. You're in full control of everything, and have unlimited power. You can ensure any changes you make have no negative consequences.

A) Would you put an end to the suffering in the world?

B) Would you alter "free will" so that people only have good (non harmful) options and thoughts?

C) Would you request worship and thanks from people? If so, would you reward worship and/or punish non-worship?

D) There is this evil guy satan who keeps messing with your plans. He causes people to be evil, and all sorts of horrible stuff. Would you remove his power to do this?

E) If you wanted to communicate with the people, how would you go about it?
