Why did my father do evil to me?

First of all, your idea of "blaming all the bad consequences on those sinners" is wrong. This kind of thinking can only aggravate your karma. Since you believe in Buddhism, you should treat all people with compassion, no matter your friends or enemies.

Secondly, it is not certain that what you and your mother have suffered is your father's sin. Perhaps, because you are relatives, even so, it means that you must have planted such a cause and effect in some world; Maybe it's not because of your father, just because you and your mother have karma.

No matter what crimes your father and brother committed in this life, there will be corresponding karma in reincarnation and they will not start robbing.

And what your brother and father did to you is not good. It must be what goes around comes around in your life. Karma will pay off, and you can become a relative in this life because of resentment or kindness.

I am also a mortal, and I don't know much about Buddhist scriptures. You can go to the temple and ask the master to read a confession and sincerely repent, which will be yours from generation to generation. I think, even if you really do this sincerely, you can't be 100% free, because you may create new karma while eliminating the past karma (for example, if you hate your father and brother so much now, it depends on your sincerity).
