I also say that Jubilee's death nor any other mutant that died after being abandoned for losing their power should be blamed on Cyclops as a result of the actual abandonment. The rest of the X-men went along with it and should be ashamed of themselves for doing so. Jubilee's situation was especially heinous as she was essentially adopted by the entire team since she was 13. Leaving Jubilee out in the cold was nothing less than her entire network of family and friends leaving her because they discovered she wasn't the proper race anymore. You cant pin that entirely on Cyclops.
