His Holiness recently celebrated his 80th birthday! 

I've read that he is very conscious of the fact that after his death, there will be much turmoil, and it's something he thinks about often. I have read/heard, though I cannot at present time point to the documentation (I can research further later and add citation, if needed), that he is aware that many, perhaps thousands or tens of thousands, will commit suicide after he dies. 

I believe the Dalai Lama has voiced opposition to suiciding for protests including self-immolation, that is violates Buddhist ethics, so my question is, if in fact many plan to suicide when he dies, Why will they act in a way that is antithetical to their teachings, specifically the beliefs of their religious leader? It seems to this Westerner a totally illogical reaction. 

Can some light be shed on this question? If I was misled about the intentions of many followers to terminate their existence as a result of his passing, then my question should be deleted. Also, this is not the same question as "What are the consequences of the 14th Dalai Lama being the last one?" because it's not about the order of things but rather about the contradiction of ethnics and action which I am unable to reconcile, hence the question.
