A rhetorical question is a question posed for effect. It is not asked to elicit an answer. A rhetorical question is most often asked to make a point or to introduce a new idea.
A rhetorical question is a good way to encourage your audience to start thinking about an issue. It is also a good way to present an idea that might be challenged if it were presented as a statement.
Rhetorical questions are a form of figurative language (i.e., unusual or imaginative word constructions).

NOT EVERYONE EXPECTS A QUESTION MARK TO END A RHETORICAL QUESTION
A rhetorical question is a cross between a question (an interrogative sentence) and a statement (a declarative sentence).
We judge that the overwhelming majortiy of your readers would expect a question mark at the end of a rhetorical question, but some might not. They consider the statement aspect of the question to override the need for a question mark. Omitting the question mark is not a popular convention, but be aware that some allow it.
