Vices are really hard things to give up. For some reasons, it gives harmonious feelings to some. It is anti-stress, comfort zone and sometimes becoming a hobby. I have met some people who have a lot of vices and they cannot give it up easily. They always have in mind that they will surely die someday, so they do whatever they really wanted to do in order to say that they live their lives in full. This is based on my observation, but all people who have lots of vices are more kind than those who does not have.
