The difference between “宁愿A, 也不B” and “宁愿A, 也要B” is which result is the speaker’s choice.
In “宁愿A, 也不B”, A is the speaker’s final choice.
In “宁愿A, 也要B”, B is the speaker’s final choice, but the speaker have to complete A to make B to come true.
According to the examples above, we learn that A and B are not all bad cases, which are based on the speaker’s views.
