For me it makes it relatively easier as I have almost nothing that makes me want to stay here.
It may not be easier for others though. One thing to consider is the fact the humans are very adaptable to their circumstances. If someone suffered for most of their life with few moments for happiness, that becomes the normal and the "baseline" for them and so they become "used" to that level of treatment. There is a sort of "inertia" that comes with being familiar with bad circumstances, it is all you know after all, you find ways to cope and endure with it even if it still a terrible situation overall, and therefore they might not CTB unless something extreme happens that pushes them over the edge or some other imminently pressing circumstance. I think this describes a lot of people on SS (this isn't meant in a derogatory way, it describes me majorly as well.)
While someone who mostly had a "good" life, but suddenly experienced tragedy, could very quickly come to the conclusion to CTB because they have never experienced that level of suffering before and have no idea how to cope with it. That doesn't mean one situation is better or worse or more or less justified than the other.
