I feel like the key to a good game as a dm is to be flexible in how your campaign / game is laid out.

Whether something is dangerous or good it will piss players off if any solution they try inevitably leads to the result you planned out, especially when it clearly makes no sense it would pan out like that.

Whether these are good or bad results they piss people off.

Players actually have fun when you can roll with the punches and they feel like their decisions are meaningful.
