They do want people to forgive--that is, if the offender went out of their way to deliberately ruin your life. Then you must forgive or you will not receive forgiveness from joke-hova for the mistakes you make. But, if you go against a doctrine in the most trivial way or make a simple mistake (and possibly panic and make another mistake because of that), there is none. In the instance of a stupid mistake where the errant one panics and makes another mistake, forgiving the whole thing can usually settle the whole thing.
But, when someone deliberately sets out to ruin your life, and joke-hova demands you forgive them, that only encourages them to continue doing that. It encourages everyone and their dog to continue abusing you on purpose, and it encourages them to abuse others. Here, forgiveness is a weakness.
