Absolutely.
And guys who would take advantage of jobbers and legitimately hurt them are huge pieces of shit. Vader, Steiners, Road Warriors, etc... The job guys are there to make them look good. Yes, they should absolutely squash them to make them look good, but the guy going over has the responsibility to keep his opponent safe. It doesn't take a tough guy to hurt someone who can't fight back.
That reminds me of Adrian Adonis trying that shit on Dan Spivey and getting his shit wrecked for it in the ring and then again back stage. Adonis was supposed to go over but he was legitimately punching/kicking Spivey and even put him in a real choke hold. Spivey got out of it and proceeded to knock him out for real, and the ref said "Adonis is supposed to go over" and Spivey said "I am changing the finish" lol. Road Warriors tried it on the Undertaker when he was in the Sky Scrapers with Spivey as well and Spivey saw them doing that shit to Undertaker, so he took a chair and proceeded to legitimately hit them with chairs as hard as he could. Taker was supposedly scared they would charge their dressing room but Spivey knew that the Road Warriors knew not to fuck with him (guy was legit on Haku level toughness) and they just said "thanks for the match!" after. Spivey was apparently an accomplished collegiate football player, amateur wrestler and was training to become a pro boxer before he got into wrestling, so you didn't want to fuck with him.
