Sometimes, an earlier risk is better than a long term one such as if the player were jumping down a mountain when night is about to fall. It may, in this case, be is a safer option to jump down, than to build their way down when night is about to fall. Risk sometimes depends on what the player is carrying with them, as rarer items could be lost in more dangerous situations. Creeper explosions can help fight mobs.
