Given that Simba is alive and well in Simba's Pride, which the show attempts to stay in line with canonically, I don't have any doubt in saying that Simba is going to survive the events of this episode.

That, and The Lion Guard is rated TV-Y, and I don't think a main character succumbing to scorpion venom would be too appropriate for the show's target demographic.
