I go back and forth on my personal feeling regarding the ethics of capital punishment itself (assuming perfect implementation, which doesn't exist). On one hand, the State can punish people who commit crimes, whether you steal their money or freedom (jail) as a punishment or take their life (execution), it seems rather comparable, just varying levels of severity.
On the other hand, I often feel that everyone has (or should have, depending on country) an absolute, undeniable right to live, no matter who he is and what he did, and the irreversible nature of death does make it different from other punishments.
Whatever you think, though, it's certainly inappropriate to consider NOT killing people disgusting. That's just a basic principle of decency. That indicates a lack of character and conscience (both of which are true about the poster in question).
Well sure, but then prison isn't exactly risk free for inmates. My personal attitude leans more towards just executing people with multiple strikes though as I implied earlier. I could see some ambiguity in terms of individual murder cases but not if someone has a repeated pattern of psychopathic behavior that makes them extremely dangerous to staff or inmates. My gut feeling is such people should just be put down.
