I feel like you're taking a very different lesson from that. He's saying God is the landlord, and the pharisees are the tenants, and when God sent them person after person to get them to behave right, they mistreated them, and then prophesizes his own death by them. Then he says the Kingdom of God will be taken from them (the bad tenants) and given to the rejected (which is a regular theme for Jesus, chilling with the social rejects and talking shit to the religious leaders).

Basically, he's not applauding the tenants. He's saying the Landlord (God) is going to kick them out of his vineyard (his kingdom) for being assholes.
