If you were near the place where Javert committed suicide, what would you tell him to stop him from taking his own life?
(Les Miserables)
Answers
Javert studied law all his life and was passionately devoted to justice. According to Javert's point of view, Valjean was the epitome of evil on the dark side of life but when Valjean spared his life, he started to doubt his own judgement of evil.
He already was in pressure of many work that he was doing and to top it all, this enormous mind boggling incident was enough to provoke his mind to accept the situation as his own mistake so had i been there near to him i would have restrained him and made him understand that one such incident can not outweigh the innumerable mistakes he made and can not completely erase his dark side and who knows he might have done that for some greater good in the future.
