S3, It's a good thing that you empathize with the sufferings of others. But karma is unfathomable according to the Bhagavad Gita. Some people commit certain actions that bring bad karma into their lives, such as violating the laws of society. So, they must suffer the consequences of their actions.
If it is within your nature, you can help others by teaching them how to help themselves. But sometimes some people are not in the proper state to learn. This is where charity comes in. So, you can help by giving some of your time and money. In the end, your good karma will return back to you in equal measure, or hopefully in many folds. As can be seen in jyotish, meditation is a form of charity. By practicing it, a person gets benefits in health, relationships and wealth.
