Well Barit, as someone mentioned, the perfectly safe flight is one that never took off.
Risk/Reward type of thing seems at play here. I have found there is always some Achilles heel in some operation. Like a main rotor in a helo coming off, or your last parchute doesn't open...that's that. I like options.
I do not mind taking calculated, mitigated risks, just hate the idea of being in position where I could've prevented something and didn't when it happened, and now it's too late...
