That kind of weather can be really hard on these plants. In my own mind I try to separate the effects of light and heat (which obviously tend to come together, in the real world). In the absence of extreme heat (our annual high temp is around 90F/32C) I get to see the effects of light without the confounding factor of temperature. In a climate-controlled setting with moderate humidity (like some people's living rooms) you get the same opportunity. We have neither heating nor cooling, so our indoors is a lot like our outdoors.
I did not mean to imply that aloes can't survive indoors without any sun, or that they can't do well given plenty of reflected/diffused light. The point has to do with tolerance. Which is something I have a particular interest in because almost all my plants will end up in a full sun situation when they are full grown.
