Oh please. Stop both siding this issue. Ukraine is the one getting invaded; Russia is the one invading. Russian society clearly has significant support for the invasion and Ukrainian society is just preventing themselves from getting slaughtered.

The onus is on Russian society to change. That definitely includes the on average relatively highly skilled people working at facilities like oil refineries. If they want a clean conscience, they should quit those jobs and leave Russia. Or better yet, sabotage the plants.
