Romans 14:12-13

So then, each of us will give an account of himself to God. Then let us not criticize one another anymore, but rather determine this-not to put an obstacle or a stumbling block or a source of temptation in another believer’s way. 

The only thing that we can control is ourselves and how we act and react. We may get frustrated with others and be tempted to criticize their choices, but our criticism does not change their circumstances. Praying for guidance for that person would. Redirect the frustration to a more powerful force and ask for help from God.
