Ya, it seems like a no brainer to say Yes. Even is Ra's said, "please run the league like I did", Oliver can just run it the way he wants when old Ra's is gone obviously. He already is only just a little better than a lot of the villains on the show, and a lot of the assassins are on equal footing as him. So he'd have a bunch of Mini-Olivers that would die for him and do whatever he says and he could make a huge difference in the world.
This show is starting to become like the walking dead, where the decisions the characters are making don't make sense and it's like the writers just figure out what they want point A and point Z to be then they say, just half as the rest. Like seriously, Oliver went to go save the guy that killed that's arguably worse than most the people in Olivers top 10 worst people killed list. The guy that killed Olivers girlfriend for nothing. Just so Thea wouldn't be a killer, even though technically she wouldn't have been a killer anyways. If your dad kills your girlfriend and you call the cops and he is taken to jail and then gets the death sentence, does that make you a killer? No one in the world sees it that way. For fucks sakes Arrow writers.
And no one believes the "I'm going to get my best friend that is a father killed because I've been fighting seriously for 7 years and I got beat by a guy that's been fighting for over 200 years. I can't believe I was beaten in a fight, I can't take that, no diggle you can't come. lol jk you can come on this suicide mission plz"
Arrow writers... for fucks fucking sake. Also if they don't reveal Maseo used the healing water to heal oliver after he should've been dead from 3 separate sources (massive punctures to vital organs, wound was moved to less vital spot lol, blunt force trauma enough to cause death from the fall and massive internal bleeding, and frostbite and hypothermia within 30 minutes of having exposed flesh on frozen ground.) Then I will still watch and love the show. But I won't be able to recommend this show to anyone else that isn't already a DC comics fan.
