What you said is RIDICULOUS. They can be aggressive when protecting their young, as any bird or anyone would be but, they do not lunge and bite. They give a warning to back off. If you do not have the brains to back off, then you deserve a bite. However, we feed Canada Geese regularly and they are not aggressive at all and would never bite us. One even allowed my husband to pet it once, although usually, we only sit by them without touching. To us, they are gentle and sweet-natured. If they are being aggressive toward someone, that someone is deserving of it.
I told him I would have happily nursed it... We worked with a state nursery when I was little and often nursed baby, opossum's, birds, squirrel's for a few days till we could take them there (3+hours away). I saw everything from dear to roadrunners up close and cage free as they worked to get them back in nature. If we're able and willing I see no problem helping a animal in this way. What beautiful pictures of kindness!
But if it's still a potential situation, I'm totally happy to help this goose get a very nice and safe home to live out his days!
