Baseball created a helluva problem when it allowed rampant steroid use in the 80s and 90s.
I agree but I don't feel that it's necessarily the players who should take all the blame.
You're absolutely right - one party is not completely to blame. It's a no-win situation. Some players juiced up because there is a big monetary incentive with contracts for players with power. Fans like to see scoring, which means home runs. MLB wants fans to attend games and generate revenue for the league. The league, in turn, looked the other way while the players were juicing so much in the 80s and 90s. It's a vicious cycle.
