Since we do not know the specifics of why these people want to assault you, we can not give advice to action to prevent more assaults. You should consider removing yourself from those situations somehow. May be even think about calling police. Get order of protection.

Karma is a big subject filled with many opinions. Many books are written about it. Who is right? IDK. My opinion (please do not hate on me for my opinion) is that what you sow is what you reap. Plant an apple tree then an apple tree will grow. It can not become an orange tree. Read somewhere if you live by the sword then you will die by the sword. Now, others think karma is an outside force that creates justice. Like, hurt someone intentionally and the universe will hurt you back. For me, there is no agency to dispense justice. Justice is a human idea. For me, karma is wrapping your essence around others. If you are kind then kindness returns to you. If you are cruel then cruelty will be returned to you. What you sow is what you reap.

Donating money does not remove karma. Clearing karma (true karma, in my opinion) requires one to remove doubts and live the life of compassion and wisdom. Living in this way will bring you mental peace. Compassion is not just empathy. And wisdom is not just knowing stuff.

Your obligation of forgiveness? Your obligation is to try to let the hate or any emotions associated with these assaults … let them go. Sometimes it requires us to forgive so we can move forward and away from these ties. This is not an easy task.

I hope you take appropriate action to protect yourself from harm. And that you can find a happier future.
