What are the three character traits of McGinty with evidences from the play script you’ve read up till now?

Powerful:

He is the Bodymaster of Vermissa Lodge, and nothing can happen in these parts unless Black Jack McGinty wants it.

"But mind my words: If you are in trouble, go to Boss McGinty.”

Vengeful:

But don’t you dare to breathe the name of Jack McGinty in connection with it, stranger; for every whisper goes back to him, and he is not one that is likely to let it pass.

Ambitious/ Greedy:

Thus it was that, year by year, Boss McGinty’s diamond pins became more obtrusive, his gold chains more weighty across a more gorgeous vest, and his saloon stretched farther and farther, until it threatened to absorb one whole side of the Market Square.
