This is not that simple though. First, Venner IS a hero. Formally it is a suicide and grievous sin, however, in his defense: at times the mind sees with clarity that the best fight is going to kill you. Then it becomes an obligation to take the fight. The confusing thing here is that since we fight in the world of ideas, and in countries paralyzed by the democratic process, that best fight for Venner in his specific personal and spiritual condition (I am not encouraging anything here), -- was a shocking act of self-sacrifice.
The subject is a complex one and I get your point, but I hope that you also get mine. America would never have been founded if they had all shot themselves. Somebody has got to stick around and fight even when the odds are against them. The men in the Alamo knew that they were facing certain death and stood their ground anyway. That sacrifice brings tears to my eyes, Venner’s does not. Did he consider all of the people who’d witness his violent act and be scarred by it, especially the children? Did he consider the damage he was doing to his family? Suicide carries a psychological impact that lasts for generations.
