The instinct to survive would override any other emotions, to the point that in order to enforce a ceasefire people have been known to kill their own kind.

Over a long enough time frame two species would cease to exist, making a war between them impossible.

Your wording(the use of "fault") implies war is inherently bad. Don't ever say war is inherently bad because it isn't.

Probability is an interesting thing to talk about, the Geth can kill, but it is not inevitable.
Using your marble analogy: If the chance of drawing a red marble is 50% and you draw a thousand blue marbles in a row, the next draw still has only a 50% chance of being red. A million draws later? 50%. 10^10000000 times later? 50%. While it would be likely, probably and nearly certain that it a couple million draws you will get a red it is NEVER inevitable.

I would like to hear the explanation behind your claim that he and his brother will inevitably try to kill each other over an extended time frame.

In some ways you are correct that all people suffer from mental illness, but from the point of view of medicine and psychology you are wrong. Mental illness in that regard is when a person exhibits behavior outside an accepted norm. For instance: while everyone can display some sociopathic behaviors in some circumstances only a few people who show these behaviors frequently(or always) are actually sociopaths.
Humans have a history of constant warfare and being fractured because we evolved as creatures who live in packs, however improved education, ever increasing globalization, and improving methods of communication are changing us. An example is the fact that in many first world countries birth rates are dropping because women are choosing to have careers instead of kids. Procreation is the second most basic instinct behind self preservation and millions of people are just turning that instinct off.
Sunshine and rainbows? No. Togetherness? Yes, like I said humans are pack animals.
