I have to SERIOUSLY defense Umbrella here.
1 - they never intended to use the T-Virus on human to make zombies and use those as weapons. Unexpencted, unwanted side-effect. NOT the main-goal.
2 - Most of their mutations they consider as "failure" or "only halfway there". For example, the later Tyrant-Models (The ones you see in 2, Nemesis and Umbrella Chronicals) work just as intended. AS WEAPONS (or bodyguards in one case).
3 - Even some of the "failures" they consider okay if they are somewhat more controllable. Namely their Hunters. Later variants, again, work as intended. Just they can't control them as they can control Tyrants. Namely, they don't different between friends and foes.
Also, Las Plagas? They were out-of-business by that time, they didn't even EXIST anymore! Those guys, who do use it, are religious zealots (and terrorists, technically).
(Sidenote: Movie-Variant of Umbrella is not related to the Games-Variant. Alice is purely made up for the movies, which have their own canon. And suck, for the most part.)
So... actually, Umbrealla would have been fine wouldn't there some nutjobs at charge as well as TWO SABOTAGE ATTEMPTS AT ONCE (Zero and the original).
And when you think about it - having a fully controllable Tyrant kind of makes you a real threat, doesn't it? And selling those off like your average tank, Umbrella would have made quite a bit of money
And regarding Weyland-Yutani... please consider that there are basically two versions of it.
1 - the one only in the Alien Movie-Francise (and the upcoming "Colonial Marines")
2 - the one in that as well as the AvP-Games.
In case of Variant 1, we have only two cases, where we know they wanted to "tame Xenomorphs". Alien and Aliens. In former case, they didn't know anything about them as it was basically the 'first confirmed' contact with them and in Aliens... well, they mostly send in Colonial Marines, which don't work for Waylend-Yutani and their job was in fact "Kill 'em all" (just that we had ONE idiot, who decided to capture one again. For unknown reasons).
Now in Alien 4, we have an entire different cooperation which clones them as Waylend-Yutani was bought up by WALL-MART (but neither was related to what happened in the movie). And yes, those scientists were the total numb-nuts.
The mentioned terraforming - yes, they got that. But it still takes about decaded, maybe centuries to actually make a planet fully habitable? Which is mentioned in the movie.
Regarding Variant 2... I don't even know, if the first AvP-Shooter is canon or not. If not, AvP2010 would be the first event after Aliens and there, yes, they were idiots. But at least they had the security... which only failed because of an unexpected EMP-Pulse from another project. I rather call them out on having too many thing at the same time going.
After that... AvP2 happens and there, yes blame them as much as you like, they now deserve it after nearly 100 years.
So, if you actually bother to do some background checks (and get your facts straight), you start to notice that both companies aren't as stupid as you make them out. Still, W-Y is obviously unwilling to learn on the long term, so... yes...
