There were number of aggravators, hired by Yanukovych to stir up trouble so yes you are correct to say that not all those who attended the protests were "normal". These Titushky were a deliberate provocation by Yanukovych and his allies, one of the series of poor decisions made by Yanukovych.
Yanukovych, after a series of poor decisions, one after the other, abandoned his presidency and fled to Russia.
The Rada decision came AFTER Yanukovych had already began to execute his premeditated exit plan from Ukraine.
