Many would expect that those who are more observant would look down and even condemn those that are less observant but that is usually not the case. We can never put ourselves in others shoes so unless they commit a major sin such as murder or rape we can’t condemn their actions and/or less observant behavior. For example one who works hard to pay their payroll feels more obligations to his/her business then someone who studies the Torah. These business owners still have to take time for Hash-m/G-D in their lives but can’t be expected to be as observant as those that don’t have this obligation.
We also don’t know how G-D weighs our individual achievements and observation of faith maybe for some it is expected but for others it’s truly a great mitzvah. To conclude let us all look in the mirror and find our own scratches before we search for those among others.
