Yes, the line "Society can be like a Double-edged sword" contains a simile. A simile is a figure of speech that compares two different things using the words "like" or "as." In this case, the poet is comparing society to a double-edged sword, implying that just like a double-edged sword has both positive and negative aspects, society can also have both good and bad aspects.
