How far would your forgiveness go? what type of person are you?

I read a lot of people hatin of each other and some, while they deserve it, don't deserve it forever, for example a reformed pedophile or a reformed murderer, should we be so hateful of these people forever or if you cheated should be hated forever, isn't it good to forgive if person wants it? whats your view? and what country are you from?
