Depends on the context.

Simple carbohydrates/sugar/sucrose have a bad name, because it’s non-filling calories that can easily result in overeating. Therefore, such products are considered ‘bad’ for the average Western coach potato.

For a high level athlete that does a lot of intense exercise, carbohydrates are a necessary fuel source and sugar is the best way to supply it. In fact, in some sports it’s impossible to consume enough energy if they athletes don’t consume sugar. If you need to perform (a competition, or a multiple day event where fast recovery is crucial), sugar is necessary.

If you’re just training for fun, you don’t need to take sugar/sucrose after a workout (but it’s not really bad either).

To summarize, you can’t classify sucrose as good or bad. Depends on the context.
