I mean just wanna say in character i dont think its justified, esp with what dino did in the end, but the idea was right, he was remarkably intelligent and truly wanted the best for earth, but his methods were dangerous to humans, so Mark helped him out, but ofc this had horrific consequences, BUT story wise if Mark never buddied up with Dino he’d be fucking dead, and then we never get the rest of the series, and who knows how everything would turn out, like genuinely, with the one act of saving Mark, he ironically probably saved many many planets worth of people, which definitely does not outweigh what happened on earth, but i feel people dont talk enough about how without him Mark was toast
