I want to make this distinction because I don't think it's obvious to a lot of people reading. You're not talking about leaving the newcomers to fend for themselves because you want to "feel the burn". You're talking about using your experience to make tactical decisions about the route, which may involve periods of separation. And you have the experience to weigh the risk of separating to scout against the risk of staying together and potentially bringing the whole group into terrain you're not prepared for. You're not just leaving them behind because they're going slower than you would prefer.
