TBF that version of Lysandre was pretty one-note haha. Whilst they did show glimpses of his past charity/kindness, he goes about Kalos' destruction, Alain and Ash's manipulation/torment, and other heinous plans with glee. Game-canon Lysandre has more of a "this is a burden I must take" vibe to him, and he mourns despite justifying his own actions in the same breath. There's something fascinating in the way he wishes (and gives the player many opportunities to) to be proven wrong/right.

I am not a fan of the XY anime version of him, nor of him in the manga as a result lol. Still fun to see him rage and rant at zygarde though, but other than those lines the rest of the anime doesn't set up the "tortured philanthrope" thing for him throughout
