First off, you're attempting to find a paradox by assuming that two worlds which are governed by different laws are one in the same. Secondly, I'm going to state facts which I thought were obvious, but clearly arn't, that will disprove anything you're trying to puzzle our minds with.
A geass command causes a person to do everything within their power to achieve the ordered end. If Suzaku is commanded to live, he will live to the best of his ability. However, if he is stripped naked and left a hundred miles from nowhere, alone, in subzero temperatures, he isn't going to live. He isn't immoral, his desires have merely been altered to force him to do everything within his power to live.
In your second paragraph you need to be more specific. There are too many variables for any real question to be posed. If you mean "Rolo will kill Shirley then die after rescuing Lelouch" then say that. Ask questions with more than one variable, because if a question has 3 variables, each having 1000 possible factors, then your number of total answers are 1000^3 or rather 1,000,000,000 possible answers.
But to answer what I can, we already know that if someone dies before their written time in the death note, then the death note has no effect. It is used to (directly) shorten a person's life. The only way it can be used to lengthen a life is indirectly (misa amani).
Lelouch DID Geass Shirley prior to the homocide, if you recall. It was about 25 episodes prior, and one of the basic rule's of Lelouch's geass is that it can only be used on a person one. Memory altering doesn't have any effect on this effect.
Your third point... Again, geassing someone to live doesn't make them immortal. It changes their will. In this case, it gives them the will to live. Thus, they do everything in their power to live. So, why wouldn't the sacrifice take place? If Rem (an entity completely unknown to L) writes L's real name in it's Death Note, why WOULDN'T he die?
Your final question: Why the fuck COULDN'T you kill a geassed person? Telling someone to live doesn't grant them immortality. Bismark's geass allows him to see into the the future, it doesn't allow him to look into the future. The main difference being that he can see what is going to happen shortly ahead of time, it doesn't allow him to look 15 years into the future to see whats going to happen. Otherwise, he wouldn't have lost to Kururugi because he would have known the Albian's specs and have abstained from battle in the first place.
This partial-quote from Billy Madison pretty much sums up my feelings towards you:
"Mr. Mariejoanna, what you've just said is one of the most insanely idiotic things I have ever read. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone on this forum is now dumber for having read it. I award you no points, and may God have mercy on your soul." |
