This is basically why you shouldn't try to fight a dog in a corner, if it has no escape it will fight to death even if there is no hope of surviving. This way, you are less likely to fight against animals with similar genes, since you got wounded the first time, and the dog's genes survive (in a different carrier). Remember that evolution happens among genes, not among individuals, so they can compete within an organism or across several animals, in ways that are detrimental to individual animals.
TLDR: you are a failure at the brink of dissuasive revenge autodestruct mode
