You aren't betraying any person or cause if you find joy in your life. In fact, that joy is what should sustain you through tough and stressful times and actions. Joy combats horror.
@amber there is a band for wich i have a certain affection who try to apply this approach to its music, i think : Idles.
They've called one of their albums "Joy as an act of resistance", and it's quite a fitting title, as their music and their shows are both full of joy and fun *and* anger and revolt.
