Joseph's brothers selling him into slavery would count, except they truly regret it and unhesitatingly offer their own lives for Benjamin's because they can't bear the thought of doing it again.
Potiphar's wife accusing Joseph of raping her because he rejected her advances is despicable, but she stops him from being executed (exposing her lies to her husband,) because she can't bear to go that far.
Potiphar seems to feel that he crossed it when he has Joseph imprisoned to avoid having to face the truth that his wife was lying, despite clearly knowing deep down that Joseph was innocent. Joseph's forgiveness clearly shakes him.
Tear Jerker: "Because I will not let our father suffer...again."
Unintentionally Unsympathetic: Jacob. The entire conflict between Joseph and his brothers could have been avoided if Jacob hadn't raised Joseph differently from his other sons and constantly telling him that he's a special snowflake who is meant for greatness right in front of Joseph's brothers. The whole "Miracle Child" song exemplifies this.
