Better than nothing, since dead people can’t seek help. It’s always best to fight the source of the problem, but until that’s achieved you should fight the symptoms. The only 2 downsides ich can think about is that a solution for symptoms can make people more reckless and some people might fear the cost. But neither should be a consideration compared to the life of someone.
You aren’t supposed to do serious work over these things. They should be a last resort imo.
