I think that Wobwob meant his post as a joke. His role lends no evidence to him having any actual knowledge of Dante being the killer. He probably chose Dante due to their recent spat.
We have to consider what we hope to gain from this random pressure. Let's say Dante is scum, through sheer luck. How likely do we think it is that he messes up and we catch him? If likely, then sure, let's do it. But I'm leaning towards less likely, personally.
