That’s what villains do. They make themselves happy at the expense of others. But it just makes them more unhappy.
Some people are fortunate enough to be born into the right family. Others have to find their own way.
If you’re lucky enough to fall in love, you have to be even stronger. Fight like a lion to keep it alive. So that on the day your love is weak enough or selfish enough or frickin’ stupid enough to run away, you have the strength to track him down and eat him alive.
