If you kill someone in self-defence, is that still an immoral act or does it depend on what form of moral philosophy you subscribe to? If an act is justified does that mean it's moral?

Is an act immoral if you are ignorant of its consequences? Would there be a difference between acts in which the truth has been arguably ignored, such as a Christian who doesn't let his kid wear a seatbelt because he has faith that God will save the child despite what statistics say, compared to an act in which a person is truly ignorant, such as the father who accidentally forgets to belt the child in or does so ineffectively by accident? Many thanks :)

Is it enough to merely respect the right of others to have beliefs different from my own without actually respecting those beliefs? Or do I need to try to have respect for the actual beliefs of others, even if I strongly disagree with them? In other words, isn't it somewhat hypocritical to talk about how you respect someone else's right to their own beliefs when you secretly think those beliefs are ridiculous or unsupportable?

If a mother gives birth to a person who goes on to become a serial killer, has she done something immoral? Wouldn't a Utilitarian say that the act of giving birth to that child will decrease the general level of happiness? Great site by the way.

How can speciesism, be immoral for people, but moral for the animals that clearly prefer their own species? If animals are morally culpable for speciesism, can animals be held morally responsible for other things like murder?

Was I morally correct in asking my (now) ex-wife to delay the divorce which she had initiated, in order to retain her much needed health insurance under my employer, until she had obtained such on her own? Or was she correct in her assertion that it would have been morally incorrect for her remain married to me, regardless of her health needs, due to the example shown to our children when she was meeting and dating others?

When you give a homeless person money is it wrong to attach conditions or have expectations about what that individual will do with the gift?

I recently read an article where a lawyer referred to something called "Role Morality" in defending his behaviour (which was not especially moral). What is "Role Morality" and what school or body of philosophy does it belong to? How is it supposed to work? It seemed somewhat bogus when presented as an excuse for behaviour that would otherwise be called immoral. Maybe there's a different moral system for lawyers? Thanks.

Is the field of Biotechnology really posing a threat to the moral and ethical values of the people? Does this field assure us to improve the quality of life and deciphering entirely the blueprints of life!?

Could you explain the relationship between intellect and morality? Obviously, from the questions I read on this site, many people expect these philosophers, i.e. brilliant men, to come up with answers about living in a good manner. But why is this assumption about the correlation between morality (applied and not theoretical) and intellect so persistent and enduring?
