The concept of antonyms for "wishing joy to" is quite peculiar, as the phrase itself implies positivity and good will. However, if one were to consider opposite words or phrases that convey negativity or ill wishes, some examples may include "hoping for misery upon", "cursing ill fate on" or "wishing sorrow to". Although such antonyms may seem harsh and undesirable, they do exist in the English language and are often used in literature, poetry, and everyday conversations. Nonetheless, it's essential to remember that spreading positivity and kindness should always be encouraged, as it can have a significant impact on one's mental health and well-being.
