Don't judge people for what they want, who they want to be with, who they chose to love, etc.
They chose to live their lives the way they wanted without even a care with what others would have to say.
Having said this, doesn't mean you can do anything you want to do.
Do what is best in God's eyes.
Nobody is perfect but we can at least give it a try to do what is good.
If we fail, we should seek God's graces and help for He is the only one who can help us live our lives WELL and BLESSED.
