Is Sherrena justified in evicting Doreen?

Legally, Sherrena is perfectly justified in evicting Doreen. She has been withholding her rent while looking for another place to stay. Doreen has a history of being evicted from previous properties for falling behind on her rent, so there is definitely a trend here. Also, Doreen has been allowing her daughter Patrice to stay with her in the apartment, much to the annoyance of Sherrena. This must be a violation of her tenancy agreement.
Morally, however, it is a rather different story. The apartment that Doreen's been renting from Sherrena is a "rathole," a place in a state of considerable disrepair. In fact, things have got so bad with the plumbing that Doreen has had to pay for it to be repaired herself. That is why she has been withholding some of her rent. Perhaps if Sherrena had shown a willingness to fulfill her obligations as a landlord and actually carried out essential repairs, then Doreen would not have fallen behind on her rent. In some places, it is perfectly legal as well as moral for tenants to withhold their rent if repairs are not made. This is not the case in Milwaukee. Consequently, Sherrena is legally entitled to evict Doreen and her family, even if doing so has profound moral repercussions.
