Predetermined Nature

If our nature is predetermined and fixed, does that mean that all of our actions are determined? If humans are, for example, innately aggressive, can we be held responsible for acting aggressively?  How does this impact morality? After our discussion in class today, I agree that even if our nature is determined, our actions are not. We may be more disposed to act in a certain way, but in the end we still have control over our actions. Furthermore, humans are not, by nature, only one thing. Humans are obviously very complex beings who may innately hold many different characteristics. For example, humans could be innately aggressive, cooperative, rational, social, competitive, etc. Therefore, even if humans were innately aggressive, there is no reason to suggest that another innate quality, such as rationality, could not overrule that quality. In other words, a person is most certainly responsible for their actions, even acting aggressively.
