What's in a word

Listening to the radio this morning, there was some discussion about whether criminals or their families should be allowed to make money from writing books about their wrongdoings. The word "profiting" was used, but also "profiteering" and I was sent to the dictionary to determine the distinction. I admit, I am still a little confused. Profiteering relates to making an unreasonable or excessive profit. Profiting relates to deriving a benefit from. Both seem to work in this context.
