Interesting to note that Clarence inexplicably avoids death as an example, but since you skipped what's arguably the most common type of demise I'll kill him myself:
- Clarence died because the dice said so. Player characters are frequently doing dangerous things, and in most rules systems no matter how skilled, powerful, or clever you are, sooner or later there is a very real chance that random outcomes will lead to a PC death. There are a few games that explicitly take that possibility off the table, but usually if there's any for of randomization in your mechanics you need to face the fact that it'll kill people sometimes. You can fudge dice to avoid that, but one of the surprising outcomes that we use randomness for in the first place is unexpected death. The whole table needs to understand that and decide if they'll accept the hand of fate, or if they'll make exceptions and if so, when and why.
Sometimes, for some people, yes. If that isn't ever true for you, it doesn't mean others are wrong for feeling differently.
