ing, which exact timing we are not wise enough to uunderstand and know when it could happen. It could be extremely complicated chains of cause & effect steps. Something only a real Buddha can decipher.
One thing we can do is do more and more good deeds (which includes kindness and no-or-less-hatred) and less & less, or even better no bad deeds. That can be a sure-fire step towards more peaceful living.
Even if Karma failed your expectation, stay on course and never easily go for revenge or hatred, which "in the long run" can only be bad for everyone, including oneself, of course.
Especially, if you persevere there seems to be always easier, more palatable peaceful alternate ways for most problems we face day in and out. Good Luck and do not be rash!
