If Jesus told us that anger is a sin, why on earth did he lose his temper so often?

The Bible lacks an important aspect called wrong for right which is beautifully explained in hinduisim. When Jesus was angry,he punished the wrong doers. This is very right, as he did not lose hs temper over useless reasons. As such, In Hinduism, it is written, 1 false statement for good is equal to 100 true statements. Imagine, If a criminal asks you where is your friend so that he can kill him, you can't say the truth, can you? If in such a condition, the bible favours truth, then Judas wasn't wrong at all, was he? He just told the truth. So, my dear friend, anger, lies, greed, etc. if used for a righteous cause, it reamians a sin no longer, it is forgiven. I do not condemn either the Bible or Jesus when I say such things, I respect all religions. The catholic church is far from Jesus's teachings, it does thrive on hipocricy, but the teaching of Jesus is pure
