Both remarks came moments apart at the party's annual general meeting in Calgary on Saturday.
Kenney gave a keynote speech in which he defended actions to protect the province's health-care system during the COVID-19 pandemic, despite the fact that some of those actions caused rifts within party ranks.
"We have made mistakes in the process and, as premier, I must take responsibility for that," said Kenney. "I know that many of you are angry with me and our government for having introduced public health restrictions at various times throughout COVID."
But Kenney said he doesn't regret his government's pandemic-fighting measures despite the anger they caused because they were necessary to protect Alberta's health system, which was on the brink of collapse.
The premier faced heavy criticism from people who thought the varied restrictions were too strong and others who thought he should have acted sooner and more decisively.
Kenney's approval rating has plummeted throughout the COVID-19 pandemic, and a series of contentious issues, such as an ongoing lawsuit against his office and political infighting, have framed much of his tenure.
He said he welcomes an upcoming leadership review but asks members to focus on the priorities of Albertans instead of internal party business. Kenney is set to face a leadership review in April but it could come sooner.
"There will be a leadership review vote next year and I want you to know I welcome that, I embrace that opportunity for accountability," Kenney said during his speech Saturday.
"We have some internal differences – every big-tent political party does and always will – but let us address and resolve those internal differences internally."

Immediately prior to Kenney's speech, newly elected party president Cynthia Moore described the UCP as a family.
"Too many of us have forgotten that we are the United Conservatives. Some of us forget what brought us together and are now focusing on what divides us," said Moore. "Compromise isn't always easy but is often the right thing to do. We must remember that politics is the art of negotiation and compromise."
When Kenney came to the stage, he was met with a standing ovation from a large portion of the room although some remained seated.
His speech inspired mixed reviews.
Brian Jean, former Wildrose leader and co-founder of the UCP, said Kenney's address won't win back support from his critics.
Jean has said he plans to run again for the UCP in a vacant seat in Fort McMurray, and that if he's elected, he will work to get Kenney out as premier.
"He's lost the trust of caucus – many caucus members – and he's lost the trust of Albertans. And the difficulty is we don't have time for him to play games to try to earn it back," said Jean.
"There have been a lot of things besides COVID that have not gone right for him."
Rajan Sawhney, Alberta minister of transportation, said Kenney set the right tone by focusing on his government's accomplishments and Alberta's rebounding economy.
Sawhney said Kenney was right not to focus on divisions, and she noted the leader is in regular conversations with UCP members.
"I have seen him hard at work. I do believe he's giving his best effort. Has everything been perfect? … No," said Sawhney. "But it's not due to lack of trying and it's not due to lack of intent."
Twenty-two UCP constituency associations have signed a letter to the party executive calling for a vote on Kenney's leadership earlier than the one scheduled for April.
On Friday, a motion that would have made it harder to hold an earlier review failed to pass with the required 75 per cent or more of the votes.
The motion that didn't pass called for raising the required number of constituency associations to 29.
