So to summarize everyone's arguments on the subject:
Miso:
Morals are learnt
CB:
Morals are learnt but groundwork for morals is with us inherently
Indi:
Genes don't know what's right and wrong therefore morals are learnt (unless right means survive and wrong means death)
Fras:
Feral children exist therefore morals are learnt and ability to empathize is through upbringing
Dalia:
All this might give some physical basis for mental illness
Vash:
The subject is boring
Eco:
Morals are not inherent, but an element of right and wrong is instinctive to us. It's somewhere between nature and nurture
Cam:
Men will screw anything on the path to #1
Bored George:
Women should accept that they are useless and stupid
Coco:
I don't like this thread
