Since WWII, Germany has always exhibited reluctance to enter any conflict. The military culture of Germany requires caution before engaging any form of war, including one that is carrying out genocide of a people. I respect Germany's self-measuring of their technology and it's distribution.
The military culture of Germany will be honorable in selling the tanks to Ukraine. I wish everyone in Germany involved with these technologies well and peace. I would be good if these tanks helped establish a peace for Ukraine.
