I Am Feeling Confused and Unsure

I feel terrible for my new landlord. Shes 65 and her husband is 75 and he has dementia. She works fulltime and she has had terrible luck with tenants. She lives on the first floor and i moved into the third. The guy on the second is really loud and inconsiderate to her.
I was in that situation with loud inconsiderate neighbors for 6 years. Thats why i moved. Now shes going through it.

She wants me to help her evict him but i kind of dont want to get involved. She wants me to accompany her to court to help her with paperwork. Idk what to do. I kind of dont want to get involved but it hurts me to see her cry and suffer.
