[Star Wars] Say there's a pair of Sith, where the master is crazy powerful, and the apprentice just sucks by comparison. But: the apprentice is great at poisoning, and kills the master like Pai Mei. Aren't the Sith getting weaker if they often kill each other in cheap ways like this?

The Sith master should be on the look out for his apprentice to kill him.  If he knew his apprentice was good at poison he was weak for still allowing himself to be poisoned. If he didn’t know this, he was weak for allowing his apprentice to hide this from him.  

Also remember if the master is this much stronger than his apprentice he should easily be able to read the apprentice’s thoughts and emotions which would make it a lot harder for the apprentice to assassinate him like that. 

It’s not just about being strong in the force but the master also has to be clever.  He should be smart enough that his apprentice can’t cheaply kill him like that.
