We all should avoid the killers of mankind. (Negative)

To transform an affirmative sentence into a negative one without changing its original meaning, various grammatical techniques can be used. One common approach is to identify a key word, often a verb or an adjective, and replace it with its antonym (opposite word), then add a negative word such as 'not', 'no', or 'never' to the sentence.

In the original sentence, "We all should avoid the killers of mankind," the verb 'avoid' means to keep away from or refrain from. To make it negative while maintaining the meaning, we can use an antonym of 'avoid,' such as 'embrace' or 'welcome,' and then negate it. Thus, "We all should not embrace the killers of mankind" effectively conveys the same message as the original, directing us to keep away from them.
