After many generations this knowlwdge coloured by fear acts on the genome for the appropriate change.
This is what I've been wondering about since you first proposed your suggestion (sorry, at this stage it doesn't even seem to be a hypothesis), just when about does this empathy kick in to influence evolution? After all antelope still die.
Now consider cystic fibrosis as another example. At my work some of the patients we monitor with CF have one or two other siblings with this genetic disorder. So here we have examples of mothers giving birth to multiple children with CF despite having experience of what this disorder can do. Conversely it has been calculated that the most common mutant allele that causes CF originated some 52,000 years ago. Can you explain this?
