I think the Supreme Court Justice issue is way more complicated than that. When going down the nuclear option, both Reid and McConnell knew this was going to happen, it was just a matter of who ended up on top.
There was always going to be a scramble for one side to change the rules, get a leg up, and pull the ladder up behind them. I suppose that's endemic to a 2-party system, but that's what happens when hard-earned consensus is destroyed. Not blaming Dems/GOP here, I'm just saying this was the inevitable consequence and it's more complicated than you're letting on.
