I am pleased to see that you now agree that Charmasa was fired for coming out. As Betty Clermont said.
And that, despite your earlier comments, there was no 'resignation letter'.
There has been no 'self-aggrandizement' by Charamsa. Quite the contrary. He has given up everything associated with being a Monsignor; with being a university professor; with being a senior official in the CDF. He has sacrificed the means to live, all the security which would have continued had he 'kept quiet' and lived a life of hypocrisy.
His coming out was an act of  total honesty.
All these things must be obvious to anyone with eyes to see, a heart to understand.
It is a mistake to leap always to conclusions that may seem obvious. Reading is important. 
Read his own explanation ('La Prima Pietra', 2016). Read, for another example, his beautiful book about Our Lady:- 'Virtù e vocazione. Un cammino mariano' (2014).
