Is Obiereka justified in taking that attitude and saying what he said to commissioner?

"that man was one of the greatest men in umofia .you drove him to kill himself;and now he will be buried like like a dog..."

obierka statement was justified,its because its the commissioner that drove okonkwo to take his own life.that is against the law of clansman and they had no right to take him down.the district commissioner have to take him down and burn him as they drove him to kill himself
