All those hands seem like you had no choice but to put your money in. You can't expect to fold your kings when you're the 90% favorite when the money goes in, so why worry about it. I'm sure you know this anyways. Micro2Macro has a good point, if you're getting frustrated by finishing OTM in big tourneys even when you played perfectly, try some 9 man SnG's or cash games. Multi tabling these should lower your variance significantly compared to 180 man SnG's.
