Since Pettigrew could hide his two-faced nature from everyone, including Dumbledore, a known Legilimens, for example when:
being an unregistered Animagus along with James, Sirius, and Remus
passing off information from the Order of the Phoenix to Voldemort
selling out James and Lily after breaking the Fidelius Charm
However, Lord Voldemort accused him of lying constantly while they stayed together at the Riddle House, could sense his lies, and here's the proof:
“My Lord! I — I have no wish to leave you, none at all —” “Do not lie to me!” hissed the second voice. “I can always tell, Wormtail! You are regretting that you ever returned to me. I revolt you. I see you flinch when you look at me, feel you shudder when you touch me. . . .” “No! My devotion to Your Lordship —” “Your devotion is nothing more than cowardice. You would not be here if you had anywhere else to go. How am I to survive without you, when I need feeding every few hours? Who is to milk Nagini?” “But you seem so much stronger, My Lord —” “Liar,” breathed the second voice. “I am no stronger, and a few days alone would be enough to rob me of the little health I have regained under your clumsy care. Silence!” Wormtail, who had been sputtering incoherently, fell silent at once. For a few seconds, Frank could hear nothing but the fire crackling. Then the second man spoke once more, in a whisper that was almost a hiss.
“I — I thought she might be useful, My Lord —” “Liar,” said the second voice again, the cruel amusement more pronounced than ever. “However, I do not deny that her information was invaluable. Without it, I could never have formed our plan, and for that, you will have your reward, Wormtail. I will allow you to perform an essential task for me, one that many of my followers would give their right hands to perform. . . .” “R-really, My Lord? What — ?” Wormtail sounded terrified
Does that make Voldemort better than Dumbledore at Legilimency?
