If Anger is one of the Seven Deadly Sins, how could Jesus have been angry yet still be sinless? (Catholicism)

Anger is one of the Seven Deadly Sins recognized by the Roman Catholic Church (the origins of which are described at this question ). However, Jesus was shown to be angry. > He looked around at them **in anger** and, deeply distressed at their stubborn hearts, said to the man, “Stretch out your hand.” He stretched it out, and his hand was completely restored. — Mark 3:5 (NIV) While the passages don't specifically say it, it certainly seems like Jesus was also angry during the cleansing of the Temple . Despite this, Jesus was without sin. > God made him who had no sin to be sin for us, so that in him we might become the righteousness of God. —2 Corinthians 5:21 (NIV) If Anger is one of the Seven Deadly Sins, how could Jesus have been angry yet still be sinless?
