Francis isn't my cup of tea. But part of the problem is I don't know what he actually said vs what the Marxist-paid media claims he said. If he spoke English, that would be a help. I don't think he has actually said anything contrary to Catholic doctrine, though the leftwing media has implied he did. I think Francis has been misled on the manmade climate change hoax, but that is his personal opinion, rather than a matter of doctrine. As far as treating the planet well, I mean, sure. Everybody agrees with that. Don't litter. Don't waste landfill space where possible, don't waste resources, recycle. I'm fine with all that.
But the leftwing media has claimed, falsely, that Francis said atheists can go to heaven as they are, presumably without repenting and that gay marriage is OK, that abortion shouldn't be condemned, and that Trump isn't a Christian. He said none of those things. The media is paid to sow division both within and outside the Catholic Church.
