Differences in forensic psychology and psychology w/ criminology

Hi,

RN I'm in the way of looking for courses and unis and making my personal statement. I have filtered my courses down to either forensic psychology or psychology w/ criminology. I have been trying to find differences in courses and the different careers they offer but everything seems to be contradicting each other.

What I'm curious is; what are the key differences between the courses and what careers do they offer?

As for what I want to do in the future and my interests, I'm interested in finding out why criminals committed the crimes they did, and I hope that one day I can interview or talk to a serial killer or someone like that to see why they did what they did, how they are as a person, their side of the story basically.

I am thinking of going into criminal journalism in the future, but also I am thinking of going into teaching psychology or being a prison psychologist.

Which courses would help me on the way to these career choices?

Thank you in advance.
