the science of psychology can make anything good or bad.

for example, someone is nice to you. 
how nice. what could be bad with that?
(let's ignore the realistic possibility of an evil ulterior motive)
to a psychologist, the situation might actually be this --

perhaps the person is nice to you because they are a masochist
who wants to cause their own anguish
by preventing their own sadistic designs directed towards you,
something their shadow side really wants to do,
so their act of being nice may not have much to do with you,
it's simply a way to punish themselves 
thereby bringing them masochistic pleasure.

of course, such a situation might be perfectly all right with you
if you're a co-dependent with a barely existent self-image and no boundaries.
it could even be the case that the two of you share
what is called a Folie à Deux, literally a ‘madness shared by two’ 
or shared psychotic disorder. This is when two or more people 
who usually live in close proximity come to share the same delusions.
if so, then you are satisfied with the situation
since you like being liked in a way that tortures you
with the knowledge that it's never been about truly liking you.
