Why would it be evil? The most basic animal instinct (and plant, for that matter) is self-preservation. It just makes sense that when a building is falling on top of you, you get out, rather than try to get everyone out. Nature knows what she's doing when she decides these traits are necessary.
The only time this should naturally be pushed aside is by parents, for offspring, which again makes perfect sense, as the second most basic animal instinct is reproduction, and babies aren't generally all that good at caring for themselves.
However, many creatures are able to look at a situation and decide if the risk is worth taking, and the price worth paying, and they act accordingly. This -is- a noteworthy action because it goes against what's normal. There are many times when I argue the validity of terms like Hero, and often I question the truth of the situation, but there are people and animals who walk straight into terror to bring someone else out, and that is impressive.
As for the aborted fetus part of your questionnaire, I see no reason stem cell research should be so maligned, but I do know that many people are thinking
> It didn't have an option as to whether its body be used for science
> It didn't choose to be aborted
> It should never have been aborted, period.
and all the et ceteras that make more sense to them.
