People end up not mattering to themselves because of those who treated them like they didn't matter combined with others filling their heads with the toxic crap mentioned above. However, the claim not to matter to oneself, in itself, can be deceptive. We can certainly feel that way, but statistically speaking most of us would flinch from harm inflicted from outside our hands, or react to harm inflicted by others, thus proving we instinctively don't simply lay there and take it by nature.

For Moriah (Malady) things, and people, matter too much, generally. It would like it if things/people mattered less. Then it would not have to wrestle against the overwhelming churning desires it has.
