The phrase "hanged upon" is usually used to describe someone being suspended by the neck until dead, which is a grim and unpleasant image. There are several other words and phrases that could be used instead that might convey a similar meaning without being quite so graphic. For example, "executed by hanging" is a more formal and descriptive way to express the same idea. Alternatively, "strung up" or "lynched" could be used to convey a sense of violence and injustice, while "dangled" or "suspended" might be more appropriate for neutral or lighthearted contexts. Ultimately, the choice of words will depend on the context and tone of the writing.
