I mostly agree; however, biological/genetic factors do not control everything. They may be involved in such traits as aggressiveness etc, but I would think that even these traits are not certain and can be changed (by many things, including your own ideas, but also many kind of external factors), and this does not include such things as "evil" and does not directly include "murder" (although it can be included indirectly, since it is related to things which are more directly affected by genetic factors, which can end up with such things). There is the question of exactly which things the biological/genetic factors affect and how much, and scientific experiments may be able to figure out some of these such things. Regardless of that, it does not mean that no murderers can ever changes (although some might not change as easily), that genetics can predict if you are a murderer with 99% accuracy, that sex or gender can predict it with 99% accuracy, etc. But, it does mean that it can have a statistical effect.
