I think that is situational.
To put it another way: If I steal something from you as a result of a trust you had placed in me, then I need your forgiveness if I am to have that trust again. But you need to forgive if you want any benefits of giving me that trust. Now, if I do something against some random person whom I've never met before and am unlikely to encounter again - then I have little use for their forgiveness. But their forgiveness will enable them to enter the same situation with another stranger that I abused.
