is this a glitch or what? (spoiler)

[nerazzurri]

ok now i gathered all 3 remaining jedi masters and went to dantooine

now no matter what i chose in the conversation in the end i release electric storm and kill them (even though i didn't chose this and i submit to the judjment etc... ) and also i have full light side meter

then kreia says i failed her etc ....

so is this a glitch or this is how it plays out no matter my choices ??
