I’m not making excuses for him, just clarifying what I think he means.
I don’t believe Pope Francis is saying Homosexuality ( as in the ACT of homosexuality ) is not sin.
Francis is saying that everyone is tempted, some towards the same sex, and some towards the opposite sex.
You can be tempted but you should NOT give in to the temptation.
Based on his words, he sees nothing wrong with a homosexual priest.
