BTW Is it bad DMing to not let a player die in some random encounter far away from the actual focus of the campaign? Cuz I'm thinking that Thok has performed admirably versus a much stronger opponent and he deserves to live. Plus he could gain Bolgrim's respect. I mean, Blogrim likes a fight whenever he's drunk, it's how he vents off. That's why Vivian and the other patrons aren't out screaming for the city watch. (well not that Vivian in particualr would go screaming for the city watch, but you get my point)
Honestly, it depends on what style of game you want to go for (and it can't be called "Bad DMing" anyway): a by-the-rules, hard-and-fast, lethal game or a more relaxed experience. The two online games I'm running tend to have some serious fights, and character death has occurred somewhat regularly, as I don't pull monster's punches (or claws, fangs, etc.

). But even with those styles, pulling a punch or ending a fight so the character(s) live should never be considered "Bad DMing." You can make it work for you, also, by making it into a hook.

[sblock=My own story about such a thing...]
Saturday online game I run is around level 6/7. They head into a swamp, don't find what they were supposed to find and start a stakeout at a place the monsters were and left. Night passes, nothing happens. They build a HUGE fire and it attracts a pair of manticores. Big fight, Druid blows most/all his spells, party badly injured, yadda yadda... Fight attracted a Juvenile Black Dragon, being in his territory. He demands tribute in either meat or coin, from inside a fog cloud the Druid created during the fight. Party doesn't pay up and makes the dragon really mad, starts a fight. They manage to beat the dragon up and it retreats...
Dragon follows them from high above until they make camp. In the middle of the night, it starts doing flybys and strafes with its breath weapon... 1 person in the group has legit Darkvision, and he only has a few throwing hammers/axes left. Since I knew they couldn't get out of this alive, Dragon offered them a deal... Deal turned out to be almost as dangerous, but it kept them from getting killed. (...Mostly. 1 almost died and the Druid's beastie-buddy got eaten.)

Plus Bolgrim was designed to be handled with the help of Alevyth and Sensalar, his CR is much higher than what Kye and Thok can handle comfortably. PLUS I'm still gauging this groups effectiveness and measuring what CR and what kind of encounters would make the game fun and not end up as a cakewalk or as a TPK. (That is to say, I'm not excluding TPK as an option, but I don't want to overkill some encounter as to make TPK the only possible outcome). Such is the trial of a relatively new DM
Sometimes high-power CRs happen when you don't mean them to... I've seen groups take on stuff that should have been nasty fights and turned it into a slaughter, when simple, weakling fights got bad thanks to crappy rolls... Part of it is, of course, the dice. Other times, it's the players not thinking things through.
Of course, it also makes a difference that you don't have a full party working on this, at the moment. Thok and Kye can only do so much... When you have the whole group together, you be a little more assured, as long as the dice don't turn one way or the other.
