Hello everyone I just want to ask did Buddha say anything directly about turning your life around? For example did he say anything about how bad people can change into good people and atone for the mistakes they made in their life.
Famous example is of Angulimala who murdered almost a thousand people and later became an arahant.
He who having been heedless is heedless no more, illuminates this world like the moon freed from clouds.
He, who by good deeds covers the evil he has done, illuminates this world like the moon freed from clouds. - SuttaCentral

Cultivate the 10 wholesome courses of action and 4 brahmaviharas, then any limited deed will be overcome by the purification of the mind.
But consider when a Realized One arises in the world, perfected, a fully awakened Buddha, accomplished in knowledge and conduct, holy, knower of the world, supreme guide for those who wish to train, teacher of gods and humans, awakened, blessed. In many ways he criticizes and denounces killing living creatures, saying: ‘Stop killing living creatures!’ He criticizes and denounces stealing … sexual misconduct … lying, saying: ‘Stop lying!’ And there’s a disciple who is devoted to that teacher. Then they reflect: ‘In many ways the Buddha criticizes and denounces killing living creatures, saying: “Stop killing living creatures!” But I have killed living creatures to a certain extent. That’s not right, it’s not good, and I feel remorseful because of it. But I can’t undo what I have done.’ Reflecting like this, they give up killing living creatures, and in future they don’t kill living creatures. That’s how to give up this bad deed and get past it.

But I can’t undo what I have done.’ Reflecting like this, they give up lying, and in future they refrain from lying. That’s how to give up this bad deed and get past it.
They give up killing living creatures. They give up stealing. They give up sexual misconduct. They give up lying. They give up divisive speech. They give up harsh speech. They give up talking nonsense. They give up covetousness. They give up ill will and malevolence. They give up wrong view and have right view.
That noble disciple is rid of desire, rid of ill will, unconfused, aware, and mindful. They meditate spreading a heart full of love to one direction, and to the second, and to the third, and to the fourth. In the same way above, below, across, everywhere, all around, they spread a heart full of love to the whole world—abundant, expansive, limitless, free of enmity and ill will. Suppose there was a powerful horn blower. They’d easily make themselves heard in the four directions. In the same way, when the heart’s release by love has been developed and cultivated like this, any limited deeds they’ve done don’t remain or persist there.
