i though i saw a plank in my eye

captious \KAP-shuhs\, adjective:
1. Marked by a disposition to find fault or raise objections.
2. Calculated to entrap or confuse, as in an argument.

The most common among those are captious individuals who
can find nothing wrong with their own actions but
everything wrong with the actions of everybody else.

The quote above sounds quite similar to this:

Judging Others

"Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.

"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? 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? 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.

- Matthew 7:1-5
