Actually, when it comes to deciding the most rational course of action there is: It's called game theory, it's very big in political science and explains alot of why politicians make the decisions we do. It boils down to organizing probable scenarios, organizing the payoffs for each of those scenarios, and going for the option that gives you the optimal payoff after factoring in the probability that exists for 'unknown' variables. Don't confuse 'rational' and 'ethical', while not mutually exclusive concepts they are not synonomys. You can make irrational, but ethical decisions and you can make rational, but unethical decisions. In the context of Mass Effect: this is why the spectres exist, so that they can make the rational, but unethical decisions without the council losing face.
Ultimately it still comes down to your goals and beliefs and there's no "right" or "wrong" about those. Someone who wants to be the best at Tennis and someone who wants to be the ruler of the galaxy would make rational decisions differently, that doesn't mean that either of them are "wrong".

Knowing that the galaxy wiped out her species the first time she has no reason to believe they wouldn't want to do the same again.
If Shepard releases her it does show that at least some are willing to give her a chance. The circumstances of the war were quite specific and involved the Rachni making all out attacks with no negotiation, by not making all out attacks the Queen would produce a different set of circumstances.

This is why later one when she contacts you she is in hiding: she knows that the moment her presence is revealed there will be an armada knocking down her door to finish the job Shephard couldn't do. And again: her first experiences in the world involved being the victim of cruel experiments at the hands of a human research company staffed by a multi-racial team. Given the communication difficulties, if released her best choice would be to build a massive war machine and launch a pre-emptive strike.
Debatable, building a decent foundation for her civilisation in secret and slowly joining galactic society would be a viable option. As the Rachni grow stronger, the cost of eliminating them also grows so the other races would be less willing to attack and negotiation would be much easier.

Now, there is room for trust... over repeated interactions. HOWEVER, this is a single interaction, Shephard knows nothing about the Rachni save that their species was nearly wiped out 2000 years ago, this one was the subject of cruel experiences, and has the capacity to build up a massive war machine over generations. The fact that this may be 100 years from now is not relevant.
It's entirely relevant, releasing her now gives her race a chance at existence and doesn't kill anyone. The fact that one day she may become a threat is only arguably a justification for eliminating her and would depend heavily on your beliefs and expectations (there's no solid "right" answer for everyone). There's a pretty good chance that she wont be a major threat (certainly not for a long time) and there are plenty of opportunities for other circumstances and events to influence the course of the Rachni civilisation. As a result, killing her now is a simple option but not necessarily the best one (especially if you believe in the right to life and are against genocide where avoidable).

When you get right down to it, when deciding to release there are only two possibilities: The queen is lying or telling the truth. Again, in an ideal world she'd be telling the truth and you would release her as that would yield a positive payoff. But the only one who can know the intent of the Rachni queen is the Rachni queen herself, and if she intends at any point in the future to make war on galactic civilization, however futile that might be, it'll result in a negative payoff for your side. Now, her best course of action would be to make peace and have the galaxy make peace as well, but again we have a serious lack of trust between both parties. Killing her however, simply results in a payoff of zero for your side: given you have no way of knowing whether she'll be friend or foe, you don't technically lose anything, but you don't really gain. Since your payoff of releasing a warlike queen is negative, the ONLY time a rational person should release her is if there is zero chance of her lying (which, as I've shown, there is a greater than zero chance of her lying).
Potential positive benefits also have value and risks must be weighed. The rational course isn't always to take a risk of zero. Whether the Queen is telling the truth or not may not even be important, circumstances will occur that may change her mind one way or the other. As I've mentioned, there are also reasons to believe that she wont do something stupid, destructive and suicidal (the fact that she's asking to be saved shows she's at least concerned about her welfare).
Killing her results in a 100% chance of her being dead and a roughly 100% chance of committing genocide. Even setting ethics aside, these results may be undesireable for some.

Again, do not confuse 'rational' with 'ethical'. If you want to argue philosophy and morality we'll be here all year, but when you get right down to it there is only ever one rational choice for any party. In this case, there is a 'right' and a 'wrong' answer.
I don't want to argue philosophy or morality, as I said there's no "right" or "wrong". In this case, there isn't a "right" and "wrong" answer for everyone, what is rational for you is not rational for everyone (regardless of ethics). There may be an answer that is "right" for you but that doesn't mean it is "right" for everyone.

Now, given that this is still just a game, you would admittedly believe the Rachni Queen is telling the truth because releasing her gives paragon points.
Paragon points don't automatically indicate a correct decision (though they generally do work out) but they do tend to indicate a decision is made on principle. You could argue that this is an indication that Shepard (of the available characters as written) believes the rational decision is to kill the Queen and the ethical decision is to save her. This still doesn't mean that Shepard's view is the only possible one. As you say though, most people don't worry too much about pre-determined character tendencies and limiting moralities and prefer to role-play their own way.
