"...First in 2004 poisoning the pro West candidate..." Zero evidence to support this statement.
"...when he bribed his puppet to abandon the EU deal..." Some call it a bribe, some call it "a better offer". EU's offer was conditional on Yanukovich having to implement austerity measures, that would have negatively affected Ukrainians. The Russian government offered a much larger amount of money, gas discounts. No austerity measures. A better deal.
