1] Disrupt Your Opponent - A slice is good way to change the pace and coax errors from your opponents, as Andy Murry has shown, or to open up the court for a weapon, like Rafael Nadal does for his forehand.

2] Buy Some Time - If your opponent is making you sweat, a slice is the perfect way to regain your footing and position on the court.

3] Blunt Hard Serves - No one uses the slice return better than Roger Federer.
