Being the one crucial vote is a hell of a lot of leverage.
Yeah, by being the tiebreakers the NDP was in a position of power. But not anymore, with this floor crossing. So I don’t understand this. The NDP could have still helped Carney out where they felt it appropriate

I think it’s important to emphasize this. People on the internet can be quick to demonize others. But OP is 15. What good is there in trying to create a divide between a 15 year old and his grandpa? There is none, not in this situation, anyway.
Besides, if we’re being honest, most of our grandparents have questionable views. There’s a massive generational gap there, and a lot of social progress has occurred since our grandparents were young. And in old age, people often just don’t have the cognitive flexibility required to adapt to these changes. And there comes a point when it might not even be worth trying to change them because they might literally just not be capable.
