"lesson we can derive from the last episode is that Almighty seems unbeatable fear death, Before , he used to tortured people, he killed often but he never felt the taste of death, till its he actually lives it."

 Mccalister is a good one , he was being smarter enough to be Red John and finally RJ is a man , an ordinary man and plus if you remember last appareance of Brett Partridge in season 5 , he talked about how Red John works through friends and proxies ans mentionned that it's shame.  , He had played a hard game by killing often and then got mad , so he surely will make mistakes one day.

The smarter side shown by Mccalister : In Episode 03 season 06 , Mccalister felt that Jane knows about the phobie from sophie miller, and thought it was Acrophobia , so Mccalister acted like he has the fear of heights to  mislead Jane , but unfortunately a pidgeon apperead in the last scene in the Episode , and Patrick Jane of course, he noticed that , and uses it in the right time.
