But this would probably only be problematic if he thought that he was capable of this without the help of the Allah. Furthermore, I don't think that he feels that he is the only one qualified to take on this responsibility but that this responsibility has been thrust on him by others. I mean, I don't know how it is permissible for you to jump to the conclusion that if someone attempts to do something that they must be megalomaniacs. Would this make all those brothers who go on Tabligh megalomaniacs as well because they somehow believe that "they" can help change the condition of individual Muslims? This really makes no sense.
