While not impossible, you have to try fairly hard to fuck up your phone like this. I'd be actively impressed if your story is true (particularly as you used the plural), and if so I'd like to know what they were specifically trying to install that fucked up their phones.
It's just statistically more likely they downloaded a malicious app from the Play Store than had any chaos side loading.
I guess it's fine to be responsible for letting the greater evil into power as long as you can tell yourself that you were morally correct at the end of the day. Because that's what you're doing. You're making a selfish moral point, and in turn actively increase the odds of a worse outcome. You feel better about yourself at the expense of everyone (including yourself).
Because what do you even gain by not voting here? The moral high ground? You just make it look like the greater evil is more desirable. At least spoil your ballot, so that it counts in the percentages...
