A quote about doing good and seeing psychiatry for what it is

This was told to me by the beautiful girl that's entered my life.
If you desire to be good, begin by believing that you are wicked. -
Epictetus

I'm really into this quote. It resonates with a concept I'd been
ruminating upon. It's about do-gooders doing bad things and bad people
doing good things, what is actually good and what is percieved good and
the relationship between knowledge of badness and actual goodness.

What do I mean by that? Well I see what Epictetus put so well is similar
to the Dunner Kruger effect (or whatever it's called) where people who
score higher tend to underestimate their performance and people who
score lower tend to over estimate their performance. In attempting to do
go those who think they do good may not be whereas those who accept
their (and they're) evil and their actions may have negative
consequences may in practice do more good.

I've recently been chatting with a cousin of mine who's recently got out
of pharmaceutical sales. She told me it was terrible what was going on
there. But the sales people, the doctors and the other supposed bogeymen
in chain of events that creates the pharmaceutical industry think
they're doing a good thing. In my other conversation about the
Liberating the NHS white paper I spoke of making sure people know that
mental healthcare is also a form of behavioural control and social
regulation and perhaps if they did then things could actually get
better. Seeing it as good may be doing more wickedness that will be
noted by psychiatric historians in the future.
