Requiescat In Pace

Some things really drive me mad.
Someone died, someone I really didn't like. Not someone I hated, rather someone I despised. I had my reasons and those are not the point here. Let me just tell you I was not the only one to hold this opinion.
I will not go as far as to say I am glad that person is gone but it doesn’t make me sad. In a way maybe it is just because that creature never had the chance to hurt me in any way that I feel this kind of indifference instead of hatred, like many others always felt.
Anyway, here in Portugal we have this weird thing when someone dies, fruit of some kind of superstition: you are not suppose to say anything about the errors, mischiefs or even crimes of a person who is dead.
Something like :”He is gone now, God shall judge him, we must not say anything lest it brings us trouble”.
In this particular case, people were discussing something the deceased had done, then they got the news of his death and suddenly the issue was taboo. Even worst: the only person that said something, along the line of better late than never, was hushed by most of the others.
To me this is either too much superstition, too much hypocrisy or too much of both.
