Is it immoral to study psychology?

I’m about to become a college sophomore, and I have already declared myself a psychology major because I am very much intrigued by why we think and act the way we do. Ultimately, I would like to become a marriage/family therapist based on my studies, though I am open for any relevant field. However, as a Christian, I have looked up "Christian" & "psychology" together on the internet recently to near-unanimous negativity. One site, in particular, has been giving me fits because the content (albeit opinionated w/ Scriptural evidence to support his POV) does all but condemn me to the pits of Hell for wanting to study psychology. I’ve included 2 links from said site below for your (dis)pleasure. Yes, I’m aware that this field was founded by less-than-perfect individuals, but what occupation hasn’t? And since God gave us (sane people) minds, shouldn’t it be necessary to explore this realm and uncover why individuals put themselves in their own predicaments? I want to use my talents to help explain the depravity of mankind, not make excuses. Serious answers only, please. Thank you. God bless.

I believe the main reason why the author of the above site is so anti-therapy is because his daughter was "forced" by his state’s child services department to ingest a drug he & his wife refused when she fell ill one time. He claims his daughter felt worse than before, and he unsuccessfully sued his state for going beyond their means, or something to that extent. Please don’t make me search the archives for that story. I may have stumbled upon an extremist site that I dare not venture in any time soon. … And of course psychology is not mentioned in the Bible. It wasn’t discovered until the 19th century. No offense. Thanks again for your understanding.

Don’t worry about it.

If psychology is your interest, then proceed, full speed ahead.

Maybe after you get your degree and a few years of experience, you can analyze some of your fellow Christians and find out why they have such an irrational dislike for your profession.
