Carlos chose to do both. Himself being a devout Catholoc (though the BBC quotes, for some "he did not appear to be especially devout"), he wanted to share the abundance of the Eucharist. As they call him, he was a "God's Influencer".
He died in 2006.
No one likes to be a saint. What do you mean by "to be a saint" ? Are you somehow inferior to others? Or are you bestowed by supernatural powers? Carlos, on the other hand, was a "saint next door". You could relate to him. If he were alive, he would be the same age as my sister.
But yes once you are under God's protection or blessing, you can suffer a bit more, take more of that life's uncertainties and vagaries. Jesus himself asked God to take away the pain if He is willingn(Luke 22:42). Yet Jesus did die a painful death.
Maybe Carlos's canonization is an invitation to be a saint in our own little ways. Even if we can't be, we can at least die trying.
