Why is it important to weigh the risk of any action against its benefits

As humans, it is important to be aware of the consequences our actions cause. For instance, if you steal an apple from a market you need to be aware that the negative outcomes (getting arrested and serving time) is far more worse than the positive (getting a free apple) therefore it is like this for most other choices humans make. So you really have to think is it worth it or is it something I need it want?
Hope this helps
