This isnt always true. You can still do everything 'right' and have a problem kid.
Actually you're right. You're doubly correct as you used quotes around "right". You never know what other causes, biochemical and psychological*, arise in a kid and cause trouble. I know enough folk who had/have serious issues in spite of good or great parenting to appreciate that kids can be the source of the problem. Such kids are the exception to the rule, but are not that rare.
But that doesn't make hitting as a policy ok. I admit I got hit a few times, probably countable on one hand. The times I remember strongly, they were not the solution, the times I barely remember, I have since forgotten because I remember they weren't teachable moments to hold on to.
I forgive parents who get drained and tired and even though trying their best, slip. Parenting is hard. There are times when hitting a kid is not that bad. But a policy of hitting a kid, an expectation to hit a kid under certain circumstances is wrong.
*It's amazing how much, in addition to other all other factors, borderline (test wise) hypothyroidism, infant-neglect, gestational drug abuse, food allergies, nutritional issues like needing extra b vitamins, can ruin a kid. But it's also very important to never excuse malice, especially willful. People who are off need to be healed, both psyco-spiritually with good parenting/moral-behavior education, as well as chemically that puts them at dis-ease with being a normal, well adjusted person. But in spite of this hope, I believe there are people currently out of the reach of the abilities of even the best parents, and as a society, just as we need to cure cancer, we need to cure the deeply malicious.
