Now I get it. You mix up two different things :
1. instinct (or as you put it, our animalistic behaviour "heritage")
and
2. apparently spontaneous
thought which is acted upon
without further conscious consideration.
Do you remember Mr. Slate and his non-arachnologist mother ? Here is what happens, in more detail, when a
Big Black Hairy Spider drops on Mr. Slate's head.
By interpreting external stimuli (light and sound waves, tactile sensations), a thought of "I have a
Big Black Hairy Spider on my head" forms in the brain of Mr. Slate. Instantly,
without further conscious consideration, that is, without second thought, without any rationalizing, Mr. Slate's
brain releases stress hormones, effectively triggering the fight or flight (animalistic) instinct which forces him to kill
Big Black Hairy Spider or run away from it. It is debatable if there is conscious choice between the two (run or kill), depending on the circumstances, and maybe it's here you might find your "evil". If Mr. Slate kills
Big Black Hairy Spider and then appears in a Spider's Court of Justice, he will most definitely be found not guilty by pleading temporary insanity.
But as you see, triggering the fight or flight instinct has no innate cause, Mr. Slate's subconscious has been
taught to be afraid of spiders by his non-arachnologist mother
as opposed to being born with this
apparently instinctive fear. You can still place a blame on Mr. Slate for not trying to overcome this fear, that is, for not trying to objectively examine the world around him and rationally conclude that spiders are not even nearly as dangerous as he has been
led to believe they are. Ignorance (and lack of empathic capacity) leads to "evil".
