Woah, hold on here. The devil has sown tares in with the wheat. Those tares will produce a lot of mayhem. It's some individuals (not all of them) in the Catholic Church that produce bad fruit.

Matthew 13
24 Jesus presented another parable to them, saying, “The kingdom of heaven may be compared to a man who sowed good seed in his field.
25 But while his men were sleeping, his enemy came and sowed tares among the wheat, and went away.
26 But when the wheat sprouted and bore grain, then the tares became evident also.
27 The slaves of the landowner came and said to him, ‘Sir, did you not sow good seed in your field? How then does it have tares?’
28 And he said to them, ‘An enemy has done this!’ The slaves *said to him, ‘Do you want us, then, to go and gather them up?’
29 But he *said, ‘No; for while you are gathering up the tares, you may uproot the wheat with them.
30 Allow both to grow together until the harvest; and in the time of the harvest I will say to the reapers, “First gather up the tares and bind them in bundles to burn them up; but gather the wheat into my barn.”’”

So they're in there until the harvest. Bad fruit from them is to be expected. Woe to them on the day of harvest.

What evil fruits are these? Do you think the sex scandals could be seducing spirits?

For instance, St. John of Kronstadt (1829–1908), who is famous, in particular, for his numerous miracles and for his writings, some of which were translated into English.

Another example: Patriarch of Jerusalem Theophilos III. He is still alive actually, so was not canonized yet, but I think he is very pious. This is his video interview in English.

As for Roman Catholic saints mentioned by you, they are criticised in this article, in a section titled «Step Three TELL ME WHO YOUR SAINTS ARE, AND I WILL TELL YOU WHAT YOUR CHURCH IS». The author is A. I. Osipov, theologian and professor of Moscow theological schools.
