I try not to judge what someone thinks he's doing but rather focus on people's actions. I'm not a Christian but this speaks to me:
Matthew 7:1-5
1 “Do not judge, or you too will be judged.
2 For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
3 “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye?
4 How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye?
5 You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.
