Importance of removing badness early

There is a nice Thirukural which means the following " If there is a thorny bush starting to grow and you/others don't want to get hurt, cut it the moment you notice it as the more you delay the more difficult it is doing to be". This signifies an important element of ethics as "Tolerance to badness" will only result in more badness.
Classical example is the "Pakistani Taliban". No doubt they were a nice handle for ISI and even US when Russians were in Afghanistan. There was no doubt in anyone's mind that this is a thorny bush but allowing it to grow was a mistake every party who ignored their threat made as a strategic blunder. Now when they have grown as a Thorny tree to threaten the world the wake up call comes. Sure it is going to be more painful to remove this than it would have been 10 years ago.
Coming back to more mundane badness we cultivate in our daily life-for example bypassing the queue. This is something a lot attempt-the assumption is that "Most will turn blind eye to this..if someone does object then we can become a rule follower". This usually results in verbal fights and in some cases even gets physical. I am not sure after this if the person who attempted to jump the queue starts following rules. But the temptation to move ahead of others where there is a simple first come first serve rule indicates a total lack of ethics. I am sure the people who attempt this will try to create political situations in office/personal life to get short term gains. This badness is something that grows with age and needs to be removed from a very young age by coaching.
Goodness requires a lot of positive coaching and internalization like a flowering plant. We need to take extra care to ensure they don't wilt under too much adverse conditions etc. Badness is like a Thorny Cactus..survives with minimal care and once rooted difficult to take out. When I read a lot of fights of Gods and demons where Demons get killed in the end-there is a subtle feeling I have that they all depict the demons within our character which needs to be won by the goodness at some point of time. The realization has to be happen within. Without being negative an introspection usually gives a few stunning badness in each person starting with how much self centered we are, how over critical we are etc. These need to be healed quickly taking a few at a time with a conscious self realization. I have started this journey and sure will try to be better than current as Souls need a more healthy mind to prosper with wisdom.
