In some comic arcs, Loki undergoes character development and makes choices that could be seen as turning good. However, it's not a straightforward or permanent transformation as his character remains complex and sometimes reverts to his mischievous ways.
Loki's character arc in the comics is quite fluid. At times, he shows signs of turning good and working towards positive ends, but it's not a black-and-white situation. His motivations and actions can vary depending on the specific comic series and the writer's interpretation.
