"Even if unskillful actions such as killing, stealing, or lying might bring short-term advantages, these are more than offset by the long-term harm to which they leave you exposed. Conversely, this same principle can make you brave in doing good. If you’re convinced that the results of skillful intentions will have to return to you even if death intervenes, you can more easily make the sacrifices demanded by long-term endeavors for your own good and that of others.
Whether of not you live to see the results in this lifetime, you’re convinced that the good you do is never lost. In this way, you develop the courage needed to build a store of skillful actions — generous and virtuous — that forms your first line of defense against dangers and fear."

In this context, I take 'skillful/unskillful' to mean 'กุศล/อกุศล or 'บุญ/บาป', am I right?
