I find wearing special clothes or doing other special things to say "I am of this or that religion" somewhat distasteful and certainly arrogant and probably hypocritical. If it is truly a free choice (not demanded by husbands and so on as a part of suppression of women) then it should just simply be ignored. I treat the local monks that way, and have had some acrimony with a few about it, but at least in this case the special clothes and shaved heads are for the enforcement of poverty and humility, but I still find it not unlike praying loudly in public, and I know monks on whom it has this effect (making them think themselves superior to others).
It is easy for a relatively intelligent person who has not undergone indoctrination to see that all "faith" (not just religious faith) is mistaken and generally wrong and often harmful. One can have opinions if they are based on valid and repeated experience, even opinions that approach belief, but never should one allow actual belief, where one has made an emotional commitment to something.
Religions make a virtue of faith, but this is seriously wrong. It is in fact a vice -- an easy way to excuse believing things one would like to believe even though there is insufficient evidence. One should only have opinions (where one can readily change one's mind without experiencing guilt or fear) when the evidence warrants it.
All that said, I do not oppose religion completely. Many of the things religions do are good. The present Pope, for example (as opposed to some of his unfortunate predecessors) seems to have a relatively open mind and is a preacher of love and tolerance and downplays doctrine. The same can be said of the Dalai Lama. Many Muslim clerics preach the same message, although unfortunately it seems most do not and many are sources of hate and intolerance. Any religion that teaches that it alone is true is likely to be this way -- in fact such a teaching makes a religion more a force for harm than for good.
It can also be argued that he was mentally disturbed in certain ways. We do not criminally punish the insane.
I am an atheist, so don't have the problem of a god dispensing justice and weighing our soul and if it is just a little too evil we go to Hell otherwise we go to Heaven (and the vast majority of people no doubt are very much on the edge).
I do, however, think we have an afterlife, or at least suspect it, given considerations of the likelihood of our being in an illusionary world rather than a real one, and when we die we go up a level to greater reality. This is a probabilistic argument recently expressed in some popular movies (where it is called virtual reality), rather stupid ones, but it seems probable, and would present a chance for what Asians call karma to do its thing -- when you do harmful things you make yourself slightly more evil, and vice versa, and this gets reflected in the more real existence to come. There is no judgment involved -- it is all rather automatic or even mechanical, and came into existence through people like us (but more advanced and probably better and smarter) creating sub-realities. Maybe it has always existed.
