Rational choice

Explanation:

Rational choice theory is a theory according to which an individual uses logical calculations to make rational choices and reach consequences that benefit them. People make choices which govern their behavior. They are based on self-interests. For example, an investor has a choice to buy one share over another based on whichever would give him more profit.

Thus, Robin would need to use Rational choice theory to study why women kill their husbands who are abusive and take a look at the pros and cons for these actions.
